Re: problem with channels

Right now, we're not able to support the concept of channel parenting,
which is what you're trying to do.  We've (artifically) restricted
Current to only handle a single channel for a given architecture /
release combination; channel parenting will be done after both the SQL
backend and Apache / mod_python frontend have stabilized at the
earliest.

        I'm working on getting those two things stabilized as soon as I
can, because I'd like to see channel parenting myself, but it may take a
while.

        Hunter's been sent a patch for a (very ugly) mod_python-based
server, and I think will be releasing it for testing in a week or so.
In the meantime, any help cleaning up the PostgreSQL backend is more
than welcome.  :)
