Not with Exchange but via .pst files.
I know you said "not with exchange", but why not just use Exchange as designed?
Hosted exchange can be had for $12/mo. for unlimited storage. Then you can have as many computers and other devices as you'd like.
2 gb limit per file.
What version of Outlook are you supporting? It's been 20GB (that's two zero gigabytes) for Unicode PSTs since Outlook 2003 for non-IMAP accounts, and since Outlook 2007 for all accounts by default, and you can configure it to be more if you'd like.
But Exchange is still easier.
