He only committed it because I asked him to, so that I could add those
very things. :-)

Yes. I was planning on using APR's mechanisms for doing this (exactly
how apache's mod_cgi works; I'll probably use mod_cgi as a guide). There
are two things to know: what program to run locally (rsh/ssh/etc), and
what arguments to pass it. This second thing is where CVS really falls
down; it presumes that your program acts exactly like rsh.

For example, something like:

# ~/.subversion/ra_pipe

pipe1 = mypipe
pipe2 = myotherpipe

command: /usr/local/bin/ssh2 user@firewall.foo.com "/opt/svn/bin/svn --server"
repository: http://internal.host.foo.com/repos

command: /usr/bin/nc 1234
repository: http://internal.host.foo.com/repos


then, one would

svn co pipe://mypipe/trunk -d monkey


svn co pipe://myotherpipe/tag/release-1 -d banana

Not that there's no attempt at a rich URL syntax.
I figure this syntax will be compatible with any
URL validators that are already in place.

How does this look?
