I will reply here with some general thoughts about multiuser support
and then below with answers to particular questions and issues you
bring up.

First of all, we currently have no proper multiuser support.  This is
only because we have not yet gotten to implementing it.  We definitely
want multiuser support and are currently in the process of writing an
academic grant to get this work funded.  But, that doesn't mean that
we can't start to move forward on this in the meantime.  We have spent
a lot of time thinking about this.  I was going to post of of these
thoughts in this email thread, but I am actually going to create a new
IPEP (IPython Enhancement Proposal) for this:


 We have recently started to use these to discuss major developments
like this.  I will do that right now and post of link to the document.
 I will also email ipython-dev to start the discussion there.
