It is ugly but you can use a vlan acl to capture on a remote span session then forward out a port that is connected back to the device for ERSPAN. Not pretty but this can be used for ERSPAN or MPLS forwarding.

RSPAN supports ACLs to filter monitored traffic. http://www.cisco.com/en/US/docs/switches/lan/catalyst6500/ios/12.2SX/configuration/guide/span.html#wp1033684 * You can use output access control lists (ACLs) on the RSPAN VLAN in the RSPAN source switch to filter the traffic sent to an RSPAN destination.
