6509 Layer 7 Application Access Control Lists? Is this possible?

I would like to know if it is possible to setup access lists on a 6509 to filter based on Layer 7 Application information. Particuarly I would like to filter out some audio streaming applications and other potentially malicious or bandwidth intensive applications that go over port 80. Is it possible to setup access lists like this on the application layer? We currently have a Supervisor 1A with PFC and MSFC. Will this work for this functionality or would we need a NAM (network analysis module) or a newer supervisor engine to do this? What do you think?

NBAR is supported for Flexwan. NBAR is supported in software on MSFC2 for VLAN traffic with 12.1.13E1. NBAR is not supported for MSFC VLAN traffic.

IMPORTANT - HW fwding for the interfaces with NBAR configured will be lost, all traffic will be forced through the MSFC2 (except ingress ACLs).
