Yeah, I think the success of Synology's NASes speaks to this - they're largely used as little home servers. And it could be even easier if someone built a box that functioned as a router and a server with dynamic DNS as an easy part of the setup. The UI would have to be really, really polished, but I think it could be done.
Symmetric home ISP connections would make these more useful, too. Sadly, that's not the norm right now, but perhaps that's because most people don't demand it.
