[nsp] 6500/7600 with large ARP/MAC tables?

Hi good people,

I'm looking for some real-life (if possible) experience terminating around
400-500 VLANs each having around 100-200 hosts, while being an IP gateway
for all of them (one gateway IP per VLAN), anticipated CAM table size of
around 60-70K entries (all hosts are IP and will be talking via this box to
the rest of the network, so ARP table is expected to be the same size). The
hardware configuration assumed is 6500/7600, native IOS (which version,
btw?), Sup720.

How likely is this configuration to run into harware limitations of the
platform or any other scalability issues? Assume that numbers above are the
worst-case scenario (no further growth anticipated).
