I'd sign that.

Acqusition has a complete different feel from Limewire, though.

I think it is because the UI of Limewire is written in Java, the one of Acquisition MacOSX native.
So it feels much smoother, and reaction times seem to be faster.

The point is "seem to be". I don't think that the core is really faster, but I get much better reactions.

Why doesn't someone write a Windows-Program, which just serves as a GUI for Limewire, thus circumventing Java for displaying?

Acq. is exactly that, but for the Mac.
And it is great!
