I'm +1 on that.

Implementing an API that exists on each platform for messaging seems
like the way to go.
Obviously only if there is such an API. I know at least C# has a
standard System.Messaging but does Ruby, Python and C++ have simlar
platform Messaging APIs?

I don't think we should be making one up, especially as some of us our
JMS API tainted.

I'd say the best way to go is to reuse already well known and accepted
APIs where we can. Is someone willing to look in to what APIs we could
