Hi Martin, thanks for blazingly fast reply :D . If time permits, I could help with coding. If done correctly, it shouldn't introduce security risks. Anyway, this can wait till 2003.
It's good idea. However, I'm not sure if I implement it. It would not be easy, I'm afraid that implementing it would introduce too many bugs. But maybe, who knows? ... :-)
It'd be nice if WinSCP could work from the home dir, using full or relative paths. That way users with rbash could use it, too. Currently WinSCP relies on 'cd' to get into dirs, and this is not possible for rbash users.
