Fair points. Now that you mention it, the CYA rationale makes a bit more sense. And yup - it's like you said, it's almost impossible to not be contributing to other Internet users in some regard most of the time, with peering really being the LCD of those situations. Hell, being the host in a Halo matchmaking game would be enough for them to nuke your service, by contract logic. Also, good idea on the tweet/etc - even a simpler option would be doing something like a text file on S3 that just flags it as on/off, and let the script poll that every so often. I think I'll do that.

Aside, but as an unreasonably paranoid person, I appreciate the candor WRT "screw it, I do it anyway" - this (personal media hosting/availability) specifically has been a pain point for a while, and with a decent pipe to the house and plenty of storage, it'd be a shame to let it all go to waste. ;)
