I did read the document, just not at the level required to consider all
of the implementation details. You can accuse me of a drive-by review,
to which I would gladly admit to. I'll try to go through in more detail
now, but my gut instinct is that you have already chosen the means that
you want to use to solve your "problem" without having spent enough time
defining the "problem" you want to solve.

You are trying to hide the implementation details from the user, which
very much goes against the grain of the Subversion core. In particular
"Implicit URLs" make some huge leaps of faith about the repository
layout which just isn't true for many sites. You have chosen two common
layouts and tried to hide the details in a new configuration file. Your
proposal is not extensible, however.

You've spent a fair amount of time coming up with the commandline
invocations, but it doesn't seem like much time in considering the
implementation details. For a simple example, some external library use
versions ala 1.23 and others user 1.2.3; how are you going to determine
which is the "latest" vendor branch?
