I was looking at firmware updates and I came across this:

That's a tad bit interesting to say the very least.  If these are basically little linux appliances, that would mean they can be modded...if you knew what you were doing of course.

yeah that is well known..  There is a guide that allows you to make it into a basic webserver.. pretty cool but not much storage..

yup  that is the  most popular version... There was a site out there that was linked on tomshardware a while back where they told you how to setup your own wireless isp using those routers... they also showed how to setup a VoIP wireless network.. allowing for the next gen of phone... The start up cost what high but after that it was pretty reasonable..
