For that >matter, modems only work most of the time -- they ain't 100%. yeah... well none of this sounds impossible.. it's just not practical.. first off, what the hell is a BeOS computer? :D I've never heard of it, and I'm a CS major.. but I'm just curious about that.. but would you be able to run two of these vinyl-data things on one of those computers? if not, someone would have to have two BeOS computers (which sound like either mini's or mainframes? if they were pc's I think I would've heard of them) and then 2 of these gizmos.. although this is quite interesting. __ __\ \ / /_\ \ \_____/ "..in whatever you do, if you can't break new ground, what's the point?" - James Cameron
