[Twisted-Python] twisted.conch.ssh.session.SSHSession.request_subsystem

[Tzury Bar Yochay]

Hi all,

I've managed to come up with a minimal sftp server implementation
which able to auth users using rsa_key

the code is available at: http://gist.github.com/37446

The point is that I am missing the knowledge needed in order to add
path control.
That is, controlling which path(s) a user can access.

at http://twisted.conch.ssh.session.SSHSession.html#request_subsystem
it appears to be undocumented

Would love to get some references, samples, etc.

Thanks in advance,
 Tzury
