Easiest way to split users into separate classes?

[Allie Hopkins]

While you can certainly do this via DHCP, why can't you do this via
the controllers?  We're a Cisco shop and the crew in charge of
wireless handle the distribution of the clients on the controllers,
not through us.

While this works, it's taking 260 lines of config, which is neither elegant nor efficient.  Can anyone think of an easier way to accomplish this?  How the 50% split is accomplished doesn't really matter.
