Thanks for the Cookie.
Here's the updated source. Will now check for "Frozen" servers as well.
I"m working on a cleaner version with a GUI, hopefully i'll be able to figure out how to make it a little more dynamic as well.
Also if someone has this running under WINE on and linux distro, let me know what missing files you have. Most of them are windows files that should be in system32 but have not yet been ported. Please list any other errors as well.

I tried loading this up in wine and I've only been able to launch it one way:
1. under terminal, run sudo WINE cmd.exe
2. navigate to your BL folder w/ DSWP in it
3. run DSWP from the terminal.
Once again, please report any missing files and errors here so that I can correct them.
