	some SFTP implementations on Win platform support version 4. That's 
defined in draft-ietf-secsh-filexfer-04.txt, and the next -05.txt bumps up 
the version further to 5 which seems to make bigger changes. In contrast to 
version 3, version 4 supports ACLs which I think is a good thing. In general 
version 4 seems to make the protocol more system independent (I guess that 
might be why 4 is implemented in apps used on Win...).
