Hi Luffy :)

We are on a development break right now... hopefully resuming soon!

When we were moving at 9 million mph, (last October) we were using the
Friefunk Firmware distribution:
http://freifunk.net/wiki/FreifunkFirmwareEnglish

And a version of wifidog, patched by Schuyler Erle that grabbed the
wireless interface's mac-address to use as a unique key to allow people
to flash FFF onto a new wrt, install wifidog, then be guided through a
'hello, we've never seen this node before' type step-by-step to get their
node onto the node databse (again, under development at
http://map.wirelesslondon.info).

One significant gotcha: We noticed that the auth-server didn't work when
you were two hops away from the node with a wired uplink direct to the
gateway, so Bruce Simpson wrote us this shell script that ran on each wrt
and prevented the client getting splashed by more than one wifidog
installation:

We had pretty much achieved proof of concept for olsr + wifidog +
friefunkfirmware... and Jo Walsh was developing some beautiful backends
to expose using the splash portal... but we had to take a break!

Anyway - hope some of this research is useful to you, do let me know if
you have any questions. What you want to do is possible, as far as I
know, and we would be really grateful for any feedback or suggestions
you might have..

Cheers,

Saul.
