Jeff,
<br /> I know...it seems counter-intuitive that AT&T made something easy. the questionaire was about 6 pages, most of it was really unncessary filler, but relatively simple. Once they did their 'magic', I was able to pass Multicast over their MPLS without an issue.
<br />
<br />again, throwing out the caveat that I've SELDOM had an application over WAN go this smooth with AT&T, but this was pretty painless. Once their piece was done i was able to effectively use it as a straight pipe with regards to using RP rolling up to the head end site.
