Fast forward 6 years and it looks like they are available from a company called Anadigm ( http://www.anadigm.com/fpaa.asp ).
This sounds like it could be a great fit for Software Defined Radio.

I wonder if you could do some interesting analog audio stuff, like building low part count multi-speaker crossover networks, etc. Then again, for $10 apiece, it probably still makes way more sense to just put a cortex or something on there and do it all digitally.
The _real_ trick would be providing the option to route the signals out of this thing and through vacuum tube stages, so you're not stuck trying to build a decent overdrive or compressor with silicon-only components.
I'd have some more ideas for lab instruments, but under these circumstances it cannot really be used for product development, sadly

One common advice is to buy from authorized sources, and looking through octopart[1], arrow is the only distributor of anadgim, with 1000 units minimum quantities.
