user14241: Are there any decentralized/shared bitcoin asset/investment management systems out there?
It should be applicable to the following case:
Many peers and nobody trusts each other. But trust is gained by investing bitcoins in that system. 
Nobody should be able to withdraw more money, than they invested.
I cross-posted this question on

I hope it's ok, if not i'll take the link out of this question.

user13963: I think that these systems maybe what you are looking for:
Open Transactions -  A general open peer to peer crypto asset system.
CounterpartyD - a New Asset system based on on Cryptocurrency
EDIT 20/05/2014
You should also check out NXT Crypto Its looking very promising the system they have developed.
