Alex,

Total agreement, and that's why I have written a user requirements 
draft and posted a suggestion of a focal point for information 
yesterday.  If the only tool you have is a BGP hammer, everything 
looks like a nail.

There are lots of other tools, but no one has ever, it seemed, 
cataloged the toolbox, and written down a beginner's guide to their 
applications.
