I could live with my cell, but I don't want to change my "home"
number. To be honest, I could probably not even answer it, and just
have voice mail email to me and I can call back from my cell.

Once your phone number has been ported to Unlimitel you would disconnect your home wiring from the telco and plug the FXS port into one of your wall outlets. Then connect an answering machine and you have a conventional phone service with call waiting and caller id.

I already have a server running 24/7. It serves media to my TV via
mediatomb, and provides storage and backup for my other machines
(mine+wife's laptops, my desktop). I may end up getting a lower-power
dedicated device, but for the moment I'll just use as much of what I
already have as possible.

I actually wired my house, so I have everything terminate to a
patch-panel in the basement. My house is voip-ready, the problem is
I'm voip-lazy.

I haven't been able to get OpenWRT to work on my Netgear WNDR3700 (it
boots, but fails to bring up PPPoE to teksavvy). I'd be reluctant to
start working on my in-use WRT54G (I'd imagine it might be a little
ram-constrained). I could probably find a used one cheap, though...

Doesn't sound so steep when you consider it would only be five months
to recoup savings from switching off of Bell? :D

I've tried to enable QoS on my WRT54G, and always found it unstable. I
have a WNDR3700 which is much faster, and has more RAM. But as I said
above, I haven't got that working yet.

I'd love to enable shaping for many reasons. Netflix & bittorrent
(bulk but not timely data) kills any online games (tiny but timely
data), etc.
