I believe you are working around a lack of feature in sshd: sshd should be 
able to choose a free port and forward that port, but, as for now, it isn't.

I've been working on a patch against 4.0p1 for a while (see thread 
http://www.mindrot.org/pipermail/openssh-unix-dev/2005-March/022829.html and 
relative follow-ups) that would implement said feature, but it has been 
rightly rejected.

Now I have to find the time to fix the bugs and recode the patch against 
latest CVS or against 4.1. I plan to work on it and have it approved within 
the end of june, but don't rely too much on that.
