Wanted to post an update:

I moved into the place that I was talking about in this thread. The wiring was a full 8 wire CAT-5 going to all of the jacks. The RJ-11 jacks were already hooked up using 4 of the wires (why? i don't know, you can do that with 2!). 4 other wires were completely unused.

So I've installed 5 of the jacks with RJ-45 and Ethernet. Wired them for 1,2,3,6 and shazam - Ethernet all around the house! I put my dsl, firewall and switch in the closet and it's working like a champ. Speed seems great, although I haven't tested large file transfers from PC to PC. The dsl is feeding the PCs as fast as if it were hooked up directly to a PC...

Thanks for the advice given previously on this thread. I didn't know what I was getting into in this place and I was as prepared as I could have been.

- Thanx
