Maybe I read his question wrong, but if he's got a 6500 in 1 closet and a stack of 3500's in a different closet, I believe it's possible to etherchannel from the 6500 to the stack. If he's staticng that he's trying to go from stack to stack, I'm not so sure unless the management software could handle it (and I doubt it does, since the ASIC's on some switches can be so picky). Maybe I'm reading too much into his question though.
