timex's Dclone Hunter is an IP finder that supports D2Multi, D2Loader, Sockscap, and hunting with multiple concurrent windows.
It's autoit.

D2Loader and D2Multi are configured for use, they have however, not been improved and will not be supported because I don't use either of them, I reccomend sticking with Sandboxie.
Don't show sandboxie indicator in the window title must be selected in each sandbox's configuration. For your sanity's sake, you may also want to disable immediate recovery, else you'll get endless popups from Sandboxie.
Running 8 Windows (4 Proxied/4 Not), all sandboxed works fine on my 2.66Ghz Single Core CPU w/ 2 GB RAM. The hunter apps use 0% CPU and ~12K memory per window, not too bad, if only D2 weren't such a hog. I didn't get realm down on any windows after 1.5 hours of running with a 180sec delay.
The config file is pretty self-explanatory. Have your windows loaded and your chars in the lobby (or ingame is fine as well), run the Starter, and off you go, pretty simple, there's no flashy/useless GUI.
If you want to stop all hunters, press F11. If you want to stop individual hunters kill hunter#.exe corresponding to your Diablo II window, they can also be individually started from the /temp directory, just make sure you run in in the correct sandbox.
If you do not exit VIA F11, make sure you've killed any processes named hunter#.exe, ProcWatch.exe, and Dclone Hunter Starter.exe when you're finished hunting/Idling.
Also included is a window renamer, it'll rename all *sandboxed* d2 windows that are configured in hunter.ini, click-n-go, pretty simple, it's for those people who manually load windows and don't use D2Catapult.
Report any bugs, I'll fix them when I can.
