I'm experienced with Cisco LWAPP enough to know it works pretty nicely. There are some quirks to be sure but for almost every wireless implementation it's the preferred solution. It's unfortunate then that both Cisco's LWAPP and Aruba's protocol (whatever that's called) are closed protocols. CAPWAP's in the works and does seem to be making some progress as an open standard, despite some concerns about hidden patent coverage in some of the standard.
Still, you'd think the standard had progressed enough to start seeing some products. Nope. I just read that Cisco's new Mobility product supports some portion of CAPWAP, which is interesting by itself. But where are the open source controllers? Controllers are really expensive! It sure would be nice to have a cheaper solution for home, for instance. This is one of those times I wish I was more of a programmer so I could just build it for myself.
