[c-nsp] 6500 PFC feature differences

[Church, Chuck]

Cisco folks,
 
    Does anyone have a decent URL that lists the various feature
differences between the PFC 3A, 3B, and 3BXL?  I found:
http://www.cisco.com/en/US/products/hw/switches/ps708/prod_bulletin0900a
ecd8017a5e7.html  which list the major stuff, but I'd like more detail.
I've read the 12.2SX release notes
(http://www.cisco.com/en/US/products/hw/switches/ps708/prod_release_note
09186a00801c8339.html) , but it's hard to summarize what works with
what.  We're most interested in a replacement for our current
Sup2/MSFC2.  It's government, so IPv6 is a necessity, MPLS might be a
future possibility (VRF support is a current need though).
Compatibility with the 16 port GBIC blades, Flexwan, and OC-12 POS OSM
is currently needed, but a migration path to the SIPs/SPAs would be nice
if that is the direction that Cisco is going to go.  I know the easy
answer would be the 3BXL across the board, but I need to make sure that
the extra $12,000 can be justified, and not just additional features
we'll never need.
 
Thanks in advance,
