You mention in your post that you will not be running trunks between the two
boxes. If that's the case, there is no need to go with 802.1q for the 6500.
There was a thread a week or so ago which discussed the pro's and cons of
ISL and 802.1q. I think the main one for ISL was per VLAN spanning tree. I
think the main ones for 802.1q are much less overheads, and an open
standard.
