I realize this is a bad idea, but in my application I think it will be Good Enough(tm). In my fiancee's apartment I have a Cat5 cable running from the living room to the geek lounge. The cable modem is in the living room because there's no cable TV connectors in any other room. I now want to put a WebTV type component into the entertainment center but it needs to be inside the firewall. Is there such thing as a Y adapter that I could split 1 Cat5 run into 2 ethernet lines? Yes, I realize it would break the standard but seeing as how one line is connecting to my cable modem (2 Mb/sec max) and the other will be 10 Mb/s, it should work. Does anybody sell these or is this just a dumb idea and I should have no business trying? -Brian
