I have recently purchased a Cisco Linksys running OpenWRT Linux. I intend to
purchase a transceiver interface too, and I'd like to use my Linksys to
control my radio as an Echolink Link.
Has anybody of you already tried something like this? I figure out, the
Linksys makes a very interesting platform as it consumes only a few watts of
power. And you can remote control it through WLAN.
I understand up to now that "thebridge" is the piece of software I will need.
Am I correct?

No problem sending it the CQiNet mailings list! I think we're all doing
this just for the fun of it, the more we work together the more fun!
I haven't played with your code, but I've looked at it and I must say
it's beautiful and elegant. I don't mind saying I've got more than a few
ideas from it. If my enjoyment weren't from developing code I would
probably just run your package or app_rpt.
Anyway I'm forwarding this to both the CqInet and thelinkbox lists so
everyone stays informed about the alternatives that are out there in open
