Where do I buy it if I don't already have it? Is it just a concept that I should be building in VFP as a COM server?

You can get more info at http://www.microsoft.com/ntserver/appservice/exec/overview/MSMQ_Overview.asp

I'm just getting into this myself. There is also a book that you can check out:
Designing Applications with MSMQ by Alan Diskman, published by Addison Wesley, ISBN 0-201-32581-0.

What's really cool is that with VFPCOM.DLL, you can bind code to the MSMQ events and fire your app when a message arrives. This is much better than looping to check the queue or doing it inside a timer.
