Calendar synchronisation

Currently I can set Outlook on my mobile to synchronise emails, contacts and diary with my work computer or my home computer. If I try to do both I end up with all my personal stuff on my work computer. I know contacts, etc can be flagged as personal, business, etc. but I have not come across a system that uses that information to allow selective synchronisation. Does anyone know whether it can be done - whether on Outlook or any other system?
