We're implementing all of these features without (as from now) any issue 
except VPLS which needs ES20/ES40 or ES(combo)
We're also using IPv4 (sparse mode with anycast RP ) /IPv6 multicast 
with embedded RP, pseudowire, L3VPN with MPLS.
As far as it goes 6VPE is also supported... (We also tested in lab, 
traffic-engineering with CRS1 in the tunnel path and it has worked at 
10Gb rate)
For whatever reason CISCO recommended a 4gb RAM RSP memory upgrade if 
the 7600 need but I'm not convinced about this recommendation.
(Note that if you need to upgrade you need to purchase 2x4Gb in case of 
redundant RSP)

Yes. WS-F6700-DFC3CXL becomes handy if you're planning to use netflow as 
the NDE(we extensively use it at full flow)  is handle by the Forwarding 
card.
(So the RSP7203CXL won't handle NDE burden) Again, more RAM would help 
to have more room for NETFLOW cache. But maybe this RAM is useful for 
another feature that I'm not awre of.

Netflow is useful and the only way (we found) to monitor IPv6 traffic on 
this platform as IPv6 MIBs are not available on this architecture.
