Wi-Fi security using linux-based router

[Harold]

I stumbled across this article several months ago.

If I am understanding this article correctly this router is a complete
Linux computer. You can access the Linux OS on the router and run almost
anything you like within the physical limits of the unit. 

I am pondering the possibility of using a flock of them as a Stone Soup
supercomputer. I will get right on it as soon as I get a bright idea
what I would do with such a machine and I can get my wife to give me a
budget for one. Sixteen units at about $50.00 each is possible.

Any ideas anyone?
