There are hosted services.
I have seen them when researching Blackberry issues.
Try a search engine for Hosted Blackberry service, I'm going to look into it soon for a friends company, so may post some details if I find something.
It is best for you to ensure that the hosted company put you onto a BES 4 with the latest patching. BES 4 allows great wireless capabilities but the early versions were full of problems, although this might not be so much of an issue with Exchange.
I would be cautious with the Firewall when this is setup. Internal setups have to be on the clean side because Exchange opens so many ports.
