I understand your hesitation to put in wires, but often its not such a big hazzle once you get started. Anyways, I never saw a post on that, but networking over powerlines should be an option as well. Prices have come down and you certainly have even more power outlets than phone plugs so maybe this is a good idea. And, if you DO go with phone wires, most houses have 2 lines wired but only line 1 in use. Line two are the outer contacts. Maybe it would be possible to use the unused line 2 and so not have any interferences? This idea came to me after my own (somewhat bad) experiences with running Rio's over HPNA with a SOny phone and a fax causing some random trouble.
