I would like to look at it, but the website seems to be gone!
Does anyone still have the code and would like to share it?
Just my $.02
Wouldn't it make more sense to use a 'standard' protocol like FTPS instead of just tunneling an insecure protocol inside SSH? This would give you also the opportunity to use real certificates! (Hm, but wasn't there a patch for SSH to use 'real' certificates?)
As the subject states: Just my $.02....
