Definitely!  At least the MOVE command is in draft stage, which helps.
I have already implemented it at FastMail (and in upstream Cyrus master)

Definitely.  There are plenty of people on the imap5 mailing list
(imap5 at who have big lists of things they want fixed.

My first port of call is the RFCs which already exist for handling
mail client/server links.  I.e. everything IMAP, SIEVE and similar.
I'm collecting my work here:

Yes, there are.  The only real questions here are:

* Authentication issues
* Firewall issues on different ports
* Offline synchronisation

The Kolab and Kontact people are doing interesting things here.  I'm
mostly deferring to them for experience in calendaring - though I'm
sure the Sunbird crew know a lot as well!
