I'm not sure I really understand all the terms here, so the following
may be meaningless :)

Is the "external agent" comparable to a proxy for a normal http URL?
If so, can you simply add the agent to the .subversion/servers file?
Then, since it is possible to specify whether a proxy/agent is used
for any given machine, you may not need a second form of the URL at
all. In addition I can use different agents for connections to
different machines, something that is inconvenient to do with an
environment variable.
