Add host to client tunneling or port forwarding (ala plink.exe -R or -L)

Add the ability to forward specified ports from the host to the client.  For example 5433:localhost:5432 - let me connect from pgadmin to the postgres database on the remote (port 5433 gets forwarded to localhost:5432 on the remote.) 

You can do this with plink as "plink.exe -R 5433:localhost:5432 username@sshost.com", but you need an ssh host running and connectable from the internet.  (Plus additional key/password management hassles.)
