Question: Is there any Object Oriented C++ library for ssh and scp. BSD license would be preferred.

I could find libssh and libssh2. But these are all procedural.

Answer: 
With libssh version 0.5 the library comes with a nice C++ wrapper. It's in the include directory and called libsshpp.h

I hope this will suite your needs. Else open a feature request.
I use cryptlib for this. It is free for Opensource and Freeware applications and easy to use.
