Hey Alan;

That would be outstanding.

Not everyone may be familiar (including me) with some of the acronyms you
through out below. I think there is a mix of those that understand OSG from
the ATLAS/CMS communities, but an equal if not greater amount of networking
people who don't support that on a day to day basis. Any pointers you can
throw out would be helpful to bring everyone up to speed.

Thanks;

-jason
