See Gruz's guide in this thread
which outlines more from the windows side and is pretty comprehensive.
You may also find some useful info in La Porta's guide in this thread
which has a lot about mini vmac - but is aimed at OS X 10.6 issues and hence quite mac specific.
Edit: I've updated Jon's post to link to Gruz's page; since I'm not totally sure where it was originally pointing. I'm sure Jon can sort it out if he sees this next time he is logged on.
