Just thought I would answer this inquiry. Yes you can have a mix of clients in ad hoc mode as the A/B/G combo card (AIR-CB21AG and AIR-PI21AG) will just use the B radio speed/data rates and will have no problem talking with other B compliant clients device. Hope this helps.
This works well. I have heard a lot of SE's out there that suggest "watch out for your performance". But you know, in my recent experience if you are deploying a purely G environment you will have little problems.
Just be aware that if you go G your effective radiation will drop because a greater portion of the spectrum is used.
I find that if I have one AP and maybe a half dozen users in the room, nobody notices. When you get maybe 20 users connected then your WLAN behavior changes and everyone pretty much runs at 'B' speeds.
