Take a look at VACLs on the Cat side. It has a capture feature that is effectively the same as a local SPAN, but without the 2 session limit. If you do a lot of RSPAN though, this wouldn't be your complete answer (VACL captures are local only). VACLs are a bit more granular in defining what's captured, if say for example you only wanted traffic destined to TCP/80, you could configure it that way.
