Hi Nick,
I just would like to add my 2 cents to the problem description.
Paste to remote machine works properly when the clipboard of remote machine is 
empty.
At the moment I copy some data on the remote machine - that value will override 
any value I'll try to paste to the remote machine.

Regards,
Yvgeny
