I haven't really thought as far as that before. I assume that once
you opened multiple sets of access batons you would divide them up by
repository. For each repository you look at URLs to determine where
to root the commit editor, then do the commit in a single pass. It's
easy to drive an RA commit editor without access batons--svnmucc does
it. You only need the access batons once the editor drive has reached
the items that have changes. It's possible that most of the current
code doesn't really change beyond replacing the single access baton
set with some sort of list or map, and a bit of lookup to map commit
item back to the right set.

Maybe. I'm a little surprised that there is interest in doing commits
to multiple repositories with one command. The commits are
independent and will always be separate. Needing to run two commands
doesn't seem like a big deal. In my scheme above I would be quite
happy rejecting the commit if it spanned multiple repositories, it's
the multiple working copies that is interesting. I suppose I am not a
typical user!
