Can one of you network gurus explain how this is legal, by Ethernet specs? I'm a little out of date, but MAC addresses were supposed to be sacrosanct physical IDs that are unique for each card. Of course this was late 70's or early 80's, and there was no danger of running out of them! I thought changing MAC would carry the possibility that you might end up with very low-level net problems, if you're exposed (i.e., what if you grab someone else's MAC.) I also thought they were issued by a standards body to manufacturers, but it seems I have a little to learn. -- "To misattribute a quote is unforgivable." --Anonymous
