The TRENDNet TK-IP101 is an impressive piece of equipment, even with the limitation of a 1600x1200 resolution. When you couple it up with an extra KVM for additional systems, it is even more so. Being able to view all of my systems at the console from out of the house or even from another room is quite a handy feature.
There are some down sides, though. Coming in with a price tag of around $400 (U.S.), it is not a cheap piece of hardware. Granted, it is meant to run in an enterprise environment as an IT connectivity device. However, there is a side market in the enthusiast world as well. As I mentioned above, I found it excellent for performing remote reinstallations as it was able to let me see all of the installation steps. I was also able to install a system without the need to switch back and forth between keyboards and monitors.
If you are in IT then the TK-IP101 is something you should seriously take a look at. If you are an enthusiast (or just a huge geek that needs all the toys) you also may want to take a look at the TK-IP101 as it just may fill a need you have never known about.
