I think if more people had reliable always-on home boxes, software devs would have a better target for distributed tech (and one would expect it'd be incumbent upon the software to figure out reachability w/ ISP/NAT issues).

Similarly, if more people had always-on home boxes, many mobile apps might be thin clients to at-home software opening up plenty of possibilities. (even a simple VNC-like proxy to an at-home web browser w/ advanced ad blocking or other extensions can help those in walled gardens who could tolerate the latency)
