Now that I have whetted my geek appetite w/what I consider to be a decent introduction to the world of QoS I think I will follow your lead tm and take a couple of weeks off, then dive into the next level.

I can see that having solid QoS is critical for modern converged networks. On to the next lobotomy!!
