I'm less worried about hijacking TLA's and more thinking about how
people use these things. They E-mail them around, publish them in
papers, write them on paper napkins, etc. It would be nice if
Subversion supported them in a way that facilitated those uses.

Okay. I guess the point is that the server configuration really
affects the choice of agent. An HTTP server works the same whether
it's accessed directly or via a proxy; since it's really the user's
problem to get their packets across to the server, the details of
their proxy configurations can be kept local. An ra_svn server,
however, may only support some kinds of tunnelling agents (SSH, or
Kerberized rsh, say), so the agent is really something everyone
accessing a given repository needs to know.
