Sharepoint is a steaming pile of crap and yet somehow it manages to pull in an ungodly amount of revenue. The big problem in that space isn't featureset, it's sales. People buy and use sharepoint because it's backed by MS. In order to beat out MS in that market you don't just need to be incrementally better you either need a product which is so vastly better it leaves sharepoint in the dust or you need something that has killer features which drive adoption and maybe obsoletes sharepoint as a side effect.
Agreed but to be honest there is nothing else that has that good integration that you can shoehorn your entire business process into.
As for startups taking this on, there isn't a chance in hell. The problem is too big to solve quickly enough to get market traction. SharePoint is big and complicated for a real reason.

Actually, all you need is a better salesperson. Sharepoint is sold by salespeople to people who have no idea of what they are buying.
