Try the ControlMaster=auto option to SSH with an appropriate ControlPath 
setting.

Example of usage at: (Googled: SSH multiplex)
http://www.linuxjournal.com/content/speed-multiple-ssh-connections-same-server

As an '-e' argument, it'd be:

-e 'ssh [...etc...] -o ControlMaster=auto -o ControlPath=~/.ssh/master-%r@%h:%p [...etc...]'
