[Red5] Terracotta

[sharrissf]

One challenge I have is I don't know all the red 5 stuff that well. Really
just the basics. I was wondering if maybe we could do a webex or something
where you could update me and a few of my guys and the terminology, the
integration  and what not. That way I can give more helpful responses :-).
Does that make sense?
