That's fine, but I won't implement it. I disagree with this solution, and
you are making a rather large assumption about being able to sniff the
network. I only use SVN over SSL, because of the ability to sniff the
password off the wire. Also, there is the ability to implement digest
authentication to resolve that problem.
