Fry's has these for $35 if you've signed up for their online promo
codes. This is a useful device if you're traveling to places where they
have wired Ethernet in the hotel rooms but not Wi-Fi (many places in
Asia are like this). It can create a wireless access point or it can be
a Wi-Fi Repeater. I think it's a good way to move things in and out of
iDevices that lack a USB port or any memory card slots. About the size
of an iPhone.

The one mode I want but is missing is WAN-side WiFi with LAN-side WiFi.
An option for DD-WRT and/or OpenWRT would be nice too. So far, the
only device I've come across that can do it all is the D-Link DIR-505L.

Interesting, I wonder if it has two WiFi radios in it... guess
I'll have to look up the details.

So the mesh people like things like 2 (or more) radios. They backhaul
to the box with the wired link this way and they want physically
seperate data paths as otherwise the interference between radios kills
performance. 1 hop, 100% performance, 2 hops, 50%, 3 hops 25% and so
on. Also, with different radios and antennas they can use point to
point on the uplink/downlink path, and omni for the local radio.

I'd suspect they have lists of routers they like.

Mikrotik RB433 can handle 3 radios. You can either buy the parts and
assemble it yourself or have someone do it for you

http://www.balticnetworks.com/mikrotik-routerboard-433-series-assembled-to-order.html

An alternative is two boxes back to back. I have a Ubiquiti radio in
station mode plugged into my Mikrotik router. When the main link to my
house fails, I can point my Ubiquiti at a distant city wifi connection
and get service

Nice but a fair bit overkill for travel/hotel usage, which is what the
OP's product and I were targetting. Ditto the double boxes.

Since I'd always be using VPN when traveling I don't really care about
having Wi-Fi WAN to Wi-Fi LAN, which would require two separate radios
so would be unlikely to be a travel product.

I'm not entirely sure you need two radios for WiFi to WiFi sharing.
One radio can do double duty i believe.

There is a number of products with this functionality, including some battery-powered ones, i.e.

http://www.hametech.com/html/product/view-31-45.html
http://www.amazon.com/WL330GE-Wireless-pocket-access-point/dp/B000TPVWX0
http://lifehacker.com/five-best-travel-routers-1452441479
http://www.pcworld.com/article/2150741/tested-6-new-travel-routers-that-can-deploy-a-secure-wi-fi-network-almost-anywhere.html

I've used HAME MPR-A1, and while it has clunky UI, it does work (including with some 3G/4G adapters).
It's also a hackable Linux platform, even with serial console ;-)

I agree it's possible, but there will be some degradation --
at least some packets will be dropped, perhaps up to half of
them, if the radio is spending 50% of the time listening to
each of two different channels.

Yes, and the instructions for this device explain that if used as a
Wi-Fi repeater the speed will be halved.

"Wi-Fi repeater mode vs. Router mode
In Wi-Fi repeater mode transfer speeds are
½ that of router mode. That is because ½ of
the bandwidth is going to read the storage
connected to SKY and ½ is for internet
bandwidth. Router mode is full duplex while
Wi-Fi repeater mode half duplex."

For most hotel WiFi situations the degradation is acceptable, especially
when the trade-off is improved coverage. I've been in a couple of rooms
where there's only one small spot that has decent signal.

having Wi-Fi WAN to Wi-Fi LAN
One use case would be to use the VPN software on the travel router
(e.g. DD-WRT) to set up the tunnel between the travel router and
the VPN host and then rely on WPA2 for privacy on the LAN side.

But the main reason I'm interested in this feature is that WiFi WAN access
at hotels are usually per device. As I carry multiple devices, a travel router
with WiFi on both the LAN and WAN side would allow me to pay for only
one device (the router) and have access on the phone, tablet, laptop, etc.
Even if WiFi were free at the hotel, it would save me from having to
register each device individually as I could just do it once by registering
just the router.

Plus something like the D-Link DIR-505L would simply replace a USB
charger rather than add to the kit. And it would also facilitate transfer
from the digicam's flash card, something that's otherwise rather inconvenient
from iOS.

If you're traveling with a laptop, perhaps configuring it
to handle both WAN and LAN WiFi is possible.

Actually this doesn't appear to be part of the functionality. It's a USB
memory card reader but you can't access the memory cards via Wi-Fi.
