LimeWire 1.8 for Linux does not contain any ads, nor does the LimeWire 1.8 for 'Other' OSs, if you are so very afraid of any ads, why don't you just use one of them? Java is cross-platform, after all, and although you would have to install it without the Install - Wizard (oh my god, it's a terminal, - I'm so SCARED!!!!) it should work with Sun's VM.
