ASR9K question please...not sure if this is OT or not...but

I have a SP Video architecture (CATV/VoD/PPV type thing) in place, testing,
and operational to some extent using 4506 and 4503 on both ends..

Digital Content Managers (DCM's) are putting out mcast video. 239dot..mcast
groups.

Mcast listeners/IGMP joiners, are Video and Audio Edge Modulators and
GQAMs.. (y'all may have heard of some of this SciAtl (Scientific Atlanta)
product line, I believe acquired by cisco about 2 years ago)

.hang in there, I'll get to my networking question.

4500's are doing EIGRP and PIM-SM to allow for support of the above end
equipment..also, the edge mods and GQAMs are group in vlan's with SVI's
inside the 4500's where I route this subnets, handle igmp joins, etc

We are upgrading our 4500's to ASR9K's..9006 on one end and 9010 on the
other end..

Guess what I found out today..$100K later..the ASR is naturally a router.
Not able to simply drop it in place of the 4500's as I've stated above, the
4500's are doing L2 and L3 combined. ASR doesn't naturally do that, as I
now understand it to be like a 2500 (old), or 3660, 7206vxr, 3825, 7513,
etc,etc..you get my point, pure router. Not like 3550,3560,6500,7600.

What do y'all think about my making the ASR9K's fit into the current
architecture of my existing 4500's by using IRB/bridge groups, and routing
the irb interfaces much like I have the vlans and svi's in my current
4500's? any cautions? This seem ok to y'all?

I'll take any advice I can get

p.s. I heard today that IOS XR 4.1 supports IRB

p.s.s. I'm new to ASRs, I'm new to IOS XR, I'm not that experienced with
IRB. IRB/CRB was something I messed with about 10 years ago for something I
hardly recall.
