Thanks for all the feedback! Will definitely be looking at the WLC failover
option.

After a bit more research discovered that the Nexus 5500s only support 25K
MAC addresses - and the ASR 1004s are VERY expensive so this option falls
away.

I had a look at the Nexus 7004 and they are about 40% more expensive than a
similar 6500 solution - but 2 line cards are probably a bit too limiting. I
am also a fearful of the WCCP implementation on the Nexuses. I read during
my research that they have recently fixed a lot of bugs in this area, but I
don't know how many still exist.

I am still waiting on the VSS support for the 4500s, but it looks like the
first version won't be available until the start of next year - and I don't
really want to use bleeding edge software for this application.

So it looks as if I am left with the 6500 VSS Sup2T solution with plenty of
room to add more line cards. The 6500s are a really great work horse. :)
