We have HA (AP and Client SSO) for separate WISM2's deployed in separate chassis without VSS (one of the big promises of 7.5...), so I might be able to provide some help.
HA in action is amazing: thousands of our clients and APs failing over seamlessly (no re-associations, barely even a ping drop). That said, we've run into multiple major bugs both with HA and with 7.5, so I wouldn't recommend moving until 7.6 or at least a bug fix for 7.5. I've heard off hand from Cisco that 7.6 is slated for before December. After working with TAC and tweaking our redundancy timers, we finally have HA when running the "redundancy force switchover" cmd. But we still aren't seeing full HA when an entire chassis reboots - so not truly HA - and Cisco has that filed as a known bug.

Is anyone using WiSM-2 in HA configuration? I'm trying to test it in my lab, and the first pass (following the document here http://www.cisco.com/en/US/products/ps10315/products_tech_note09186a0080bd3504.shtml#guiconfig) was unsuccessful. I'd like to get some perspective from someone who has made it work successfully. Are you using the HA in a single chassis, or VSS? Email me off list, if you can shed some light...
