They could be looking to just cover their legal butts. ie: Sure, go ahead, run Tor, so long as torservers is standing up and being the active respondant, so they can then legally point the finger at you. Up until they start taking heat from their own upstream. I need to reread the topic again, but in the US, for example with DMCA, I think the carrier can in fact let you live (by taking the agnostic, hands off, third party approach), so long as you are interacting directly (cc: carrier) with the complainant, even up to and including court battles the complainant would need to shut you down. Excepting of course any actions lodged directly by the complainant against the third party carrier. I actually think "hands off" is the smart position for the carrier to be in, but few seem to operate that way. For the cases where a potential hoster does not outright welcome Tor by name when pointing them to torproject.org... sending them common examples of the 'abuse' scenarious you expect and how they will be 'handled' by torservers as the 'responsible' party might help. You can also say something like "torservers is prepared to sign a" release, indemnification, acceptance, memorandum of understanding, etc. Either that or put them on the short term, pay and get booted, plan :) Which is actually bad practice as it would leave more of a bad taste regarding Tor, as opposed to being upfront, and nobody wants that.
