Okay, I've just implemented something similar to this. You can provide
dbfiles as a function, taking zero arguments, and returning a tuple in
the normal format. I've put an example of how to do this in
config.py.example. Synced to monotone.ucc (rev [b5d299ba8b]).

The function with zero arguments is to avoid the list of databases
being computed every time something imports config.

Done and synced to monotone.ucc, see [0ab839402dabfe75e..]. It's not
configurable; just edit the template. You can easily commit to viewmtn
on a private branch, and propagate from the main branch to yours to
upgrade.

The description is escaped, so you can't put HTML in. Easy to change,
just look at the #filter stuff in other templates.

That definitely won't work any more. urls is now built when the
ViewMTN instance starts up,
and globals() has been defined by a hash built the application.

Try replacing it with:
  from viewmtn import assemble_urls
  urls, fvars = assemble_urls()
  pplication = web.wsgifunc(web.webpyfunc(urls, fvars))

I haven't tested that - unfortunately I'm overseas and don't have a
convenient machine to try  and replicate the problem on. You'll need
the very latest rev, [0b434d71ff24d..]

I'll be traveling the next few days and possibly out of contact.

Have fun
