Its possible.  Make sure you understand that you're doing this for the
shared namespace though, otherwise you almost certainly want a more
traditional IMAP proxy like perdition.

Note that the murder was never intended to work in a geographicly
distributed fashion.  There may be lurking bugs/performance issues (though
based on how it actually works, I don't expect this).

Yes.  Ken debugs complete murder configurations on a single laptop.

Of course, I don't recommend it (now you're costing yourself 2 IMAP
processes per connection on that machine instead of 1)

I think you should be sure Murder is what you want before you jump into
it.  It solves a very special problem that most people don't have.
