A single ip kvm can easily cost $500.00
When I saw this
gumstix product I thought someone either has or will eventually make one.
Guided from the cost (+overo com) of the hardware above you can probably use for such a project it seems you will be spending just as much and cost you more for something you aren't guaranteed will work as desired.
So, I was wondering if anyone ever ran across comparable hardware or a solution, my first impression was ip kvm's are grossly overpriced.
