Two MX records for one domain?

It is possible to have two distinct email servers (for two sets of non-overlapping addresses) for the same domain?

I think this is impossible, but I could be wrong.
I have a domain, example.com. I would like to be able to give my users the option of using one of two services for their email.
On the one hand, we have the default setup where the DNS MX record for the example.com and mail.example.com resolve to the ISPs mail server, which provides POP/IMAP and web mail.
On the other hand, if I rewrite that MX record I can use a service such as Windows Live or the new Gmail on your own domain service and allow my users a slightly nicer experience, and a lot more storage space than I can afford to supply.
The problem is that some accounts already forwarded to regular gmail accounts, and I don't want to disable that.
So what I would like to do is have a few accounts run through the 'other' service (say, Windows Live) and the rest (including catch-alls and non-existent) stay on the ISPs server.
I have access to the DNS and can make pretty much any reasonable request of my ISP in terms of changing server settings, but is this even possible?
The web based admin package my ISP supplies allows me to create mail forwards for accounts, but they forward to other email account, I guess what I need to be able to do is forward specific accounts to a different server. Is that possible?
It's easy enough to trick the servers for outgoing mail, as you can send email from anywhere as anyone, the problem would be ensuring the incoming mail for email@example.com would go to the ISP, and at the same time send firstname.lastname@example.org to hotmail.com/gmail.com
