MSMQ Recieve / Send ****ts

Hi,
I have an application deployed on two servers(A and B). They use MSMQ
to recieve and send messages. the msmq's are on server A. The hosts
handling the recieve and send on these msmq's are clustered. Should I
just enable the hosts on server A or can I enable hosts on A and B for
better availability? Or can I have a few hosts running on A and a
different few running on B for better performance.

I read on a few sites that mention remote msmq reads are not
transactional but also saying that we could use clustered MSMQ for
better availability which contradicted each other (Or may be its just
my understanding of them thats not clear).

All help is great help

Thanks
