I had already played with the control path options and wondered why forwarderd 
connections could not be added or canceled this way. Will that included in 
the next openssh release? Can I help to implement it (haven't looked yet at 
the source)?

Is it right that in a connection made via control path the escape character 
does not work?

console1:
ssh -MS ~/.ssh/ctl x at y.z

then console2:
ssh -S ~/.ssh/ctl x at y.z

then ~. in console1 will abort both connections as expected but ~. in console2 
will be transfered literally. (OpenSSH_3.9p1, OpenSSL 0.9.7d 17 Mar 2004)
