Sweet, feel free! It's be pretty cool if you could put it up in this thread to - y'know, as a central hub for portable ADB prompts.
If you want, you could do a port/repackage. Basically it's just caling the ADB executable, executing adb command, and looping back to ask for more input. Simple, really. Easier than cding to the directory with the exe and all that wankery.
The best thing to do by means of disribution would be to package it in a .dmg and make it call a script to to the input-execute-loop thing (I don't know much about Mac file extensions). If you understand Windows batch code, you could try interpret adbprompt.bat to work with the Mac's native shell code - which I think is .sh, correct me if I'm wrong.
So yeah, port it if you want, send it my way through a PM (upload it to mediafire or something), and I'll put it up - with appropriate credit of course :P
