So I finally got around to requesting that two more network ports in my cube get turned on. Today they came around and turned them on, meaning that the extra laptop and the mac laptop I have had sitting around, now have network access and are useful. Since my desktop got replaced last week by a laptop, I've been running it with two screens (laptop and monitor) since then. Now that I got network access for all the computers, I set up synergy on all three and I am now running three computers, three OSs and 4 screens all from one keyboard and mouse.
And I can copy and paste proxy settings from one machine to another, so I didn't even have to type that stuff in. So far I don't know what I'm going to do with this setup, except perhaps get some kind of a tan from all of it, but it's pretty cool and people have been impressed so far, especially with the copy paste abilities across computers and across disparate operating systems.
