Arriving late to this thread and won't finish it before responding

For one, as I said before I don't want to leave my G5 on all the time -- it sucks up way too much electricity. Having it shut down using energy saver would be ok I guess except I never know what random show I want to record until the day of when I look. That would mean I'd have to constantly be changing the energy saver shutdown time every day to make sure it's on to get my program(s). Seems like a big hassle and kind of defeats the purpose of being 'easy'.
EyeTV software will automatically wake up a sleeping Mac a couple minutes before a scheduled recording. Works fine here, except if the "Require password to wake this computer from sleep or screen saver" Security preference is enabled the system can go back to sleep when the login dialog times out before recording has started. I work around that by FUSing to my wife's account since it'll reactivate its login without a password after sleeping. It's primarily her Mac anyway so sometimes that FUS is unnecessary, or it's become second nature to FUS back after temporarily switching to my account for doing EyeTV-related or other tasks. Sometimes I'll manually sleep it; others times I just leave it run and let it sleep whenever it feels like it (which is mysteriously unpredictable).
I'm conscious about electricity usage with rates being relatively high here. I've been surprised how little difference certain changes make on a monthly bill, and how doing nothing obviously different sometimes "causes" a significant increase/decrease. I don't over-attempt to ultra-conserve now that I've seen how it basically averages out regardless what I do. I'll reevaluate if/when I get a Mac Pro or other energy-hungry system(s).
Also if I'm downstairs watching TV I don't want to think about having to go back up to restart my Mac, only to go back down to watch a show that's on my Mac [upstairs]...again, not worth the trouble day in and day out.
Not being able remotely wake a sleeping Mac downstairs to watch EyeTV recordings upstairs (via EyeHome) is an issue though the occasionally bit of stair exercise to do it has never bothered me; I'll often do it as quickly as possible without tripping or clobbering some body part on a wall.
I had a workaround using my old iBook to remotely log in wirelessly to my iMac that typically runs 24x7, then running wakeonlan to wake up the eMac over a wired connection. I also used to remotely control iTunes/AirTunes with that iBook before its display stopped working last year.
