Has any developed a tie in for IBM's WebSphere MQ for Workflow. From what I can tell there are many ways to access IBM MQ facilities.

Some of the APIs directly supported by IBM are:
IBM Message Queue Interface (MQI) for C, COBOL, PL/I, Java, Rexx, RPG, and C++
Java Message Service (JMS)
XMS for C/C++ and .NET[4]
.NET
Representational State Transfer
SOAP

Additional APIs (not officially supported) are also available via third parties, for example:
Perl interface (developed and contributed by Hildo Biersma), available from CPAN.
Python (programming language) interface PyMQI (originally developed by Les Smithson), available from PyPI
Windows PowerShell

I am assuming since there is .net and Java a custom activity should be able to be written or we should be able to use the JRA APIs in the SDK. Has anyone done this yet?
