Does Signal R make MSMQ, ActiveMQ, nBusService and MassTransit obsolete in web applications?

on .NET platform we now have a new kid on the block. Signal R for those who do not know, it simply implments a push mechanism and makes it possible to call client side JS code from the server side and a single app with 100s of clients connected, can communicate with them directly rather than wait for a call, or periodic calls from them.

Does this make the MSMQ, ActiveMQ and other such enterprise bus systems and messaging systems obsolete? because the purpose of Signal R, MSMQ, ActiveMQ, Zero MQ, MassTransit is the same. to make the server push notifications to the clients (the subscribers)
