The binary works fine on my PowerBook and G5 here at work... though as you will notice, neither are Intel based.

So if anyone has taken the plunge, let me know if things work. In theory it may actually have less problems because it should be using the native little-endian code (as in perhaps network stuff work?).
So without further ado...
