It's a decent platform but it's an attempt to address a lot of different issues in one platform. If you're pure quant you're probably better off building something custom and plugging in QuickFIX (which marketcetera uses for FIX connectivity), particularly since last I checked its feed handlers (a right bastard to get right) aren't particularly sophisticated. If you're running a trading floor there's a plethora of issues you'll face that aren't currently solved by it. The use of ActiveMQ over AMQP also doesn't make much sense anymore, AMQP is built from the ground up for financial messaging - both orders and feeds - and has a very robust OSS implementation (RabbitMQ).
