Which is precisely what I have done. It's incredible how much you can wring out of a commodity 6 
core processor and 16GB of ram. It also makes it easy to automate backups. Send the VM an ACPI 
shutdown, back up the file and start it back up.

I've been doing some pretty large layered work with GIMP (designed to be printed at 300DPI A1) and 
it's much nicer to do that on a VM in the server tunnelling X over ssh than it is on a Mac Mini with 
only 2GB of RAM. When you can fire up a VM with 4 cores and 12GB of ram it makes things much quicker.

No, I'm pretty sure you can use CalDAV without the mobile connector, though I can't get that to work 
on Pam's iPhone. The ActiveSync works, but I just can't get CalDAV to see my shared calendars. It's 
all flawless on the BB through the BESX though.

I played with a few IMAP clients on various phones and there are some pretty good ones out there. I 
was using an IMAP client on the BB for a while connecting to Dovecot, and the IDLE support worked 
really well. Bandwidth was low and it was pretty quick.

I'm using the Zimbra Desktop client. I have to say (java bloat and all) it's really very nice. 
Having said that, their web client is almost as good on firefox.

I've no idea what exchange costs to buy, but everyone I know that runs it reckons its damn expensive 
to keep running.
