I guess it was an "unknown feature" for me. I couldnk't think where else to ask it.

But as to your answer (thanks, by the way), maybe just having some additions to the Registry wouldn't count so high on an employer's 'no' list as actually installing it. After all, many things are written to the Registry all the time -- recently saved documents, history, etc. I supposed it probably wrote something, because I had the feeling it would want to know about my connection and whatever else it asked when I installed it.

BearShare and AudioGalaxy seem really 'clean' in that regard, however.
