If you want to Airplay mirror the content from your iMac unto your iPad. You could use a VNC such as Splashtop or logmein. It isn´t airplay mirroring, but it works similarly and better since you can controll your Mac directly from your iPad.
Now if you want to airplay mirror your iPad content unto your iMac, you can use AirServer.
But there will be horrible lag if you use such Remote Desktop solutions. At least from my experience. Hell, even with AirPlay mirroring from iPad to speakers, I usually have 1-2 second lag. I don't think such over the air programs are ready for prime time yet.
