Hello,
I would like to propose that you take a look from a different perspective (and I thought from the mail subject the question will be about that) on this.
To run an exit node from a VPS provider is not safer -- TO YOU -- than running an exit node from your personal home connection.
This man[1] had his house raided and his computers confiscated because of a Tor Exit node that he was running **NOT EVEN AT HOME** but in a datacenter, in a different country, on a server that he was renting (of course in his name).
From what I gather from discussions surrounding that incident, the only reasonably safe way (again - to you) to run an Exit Node, is to do so on an IP range that's SWIPed to an LLC or a similar company, and not just has one physical person (you) responsible for it.
