Yes.

No, it allows concurrent connections. However, embedded on Linux (at leaast
for FB 1.5.x) requires more synchronization - one thread per library at a
time. Embedded for Windows allows one thread per connection at a time.
Vulcan should relieve the Linux requirements.

You have to check the performance degradation with a time. The garbage
collection is an important issue. So let your system run for few hours and
then check it again.

Just create a plugin for ActiveMQ and you're done :)
