Running web-based services from home

Danny O’Brien’s been talking about making good use of an always-on home connection to replace all those web-based services we’ve become dependent on and that are about to start charging. I’m looking forward to seeing his conclusions. So far I’ve got that ‘Apache installed here’ screen up on the Cube in our kitchen but I’d love to be able to fix it so I can see my MP3s from the office (or wherever). Only total UNIX-fear prevents me from sorting it out now. Thinking about it, though, with my kids playing Flash Tweenies games, regular power cuts and reboots and a very flakey Wi-Fi connection do I really want to be relying on a home machine when I could be paying Apple $100 per year for something that really is ‘always-on’.
