According to the Feature Navigator, they haven't released IOS for Sup32
yet, but it is obviously planned.  I did, however, stumble across some
literature on CCO on configuring Sup32 in 7600 with IOS.

Yes, the Sup32 can (if it's running IOS) handle a full table, it's specs
say 256,000 routes...does that mean it can handle 256,000 actual routes
or 256,000 BGP table entries?

The Sup32 does indeed look pretty nice, supporting MPLS, 10GE and if 
it's as affordable as a 7200/NPE-G1, it's a real option for a lot of
scenerios.  I'm assuming making it do POS over STM-1 would mean buying
FlexWAN, extra software licenses, etc., making it a lot more expensive
than a 7200 doing the same?
