Please do! I think something like this could be valuable to a lot of small to medium companies who atm can't resist subscribing to Google Apps (50,- per user you could have instead). I think with a service like that, the main goal would be to stay as simple as possible while still offering the "Exchange" integration with people's current infrastructure. I would do the user side web frontend last and concentrate on a simple but empowering foundation plus administration interface first. Clearly with the PSN breach and all the bad press Google, Apple & Co. are getting with location/mobile I can see a shift in people's minds towards more privacy and security similar to when people started to get used to anti-virus/firewall software. 2011 - Devops galore.
