Pardon my ignorance, but I thought it fruitful to ask: Are there any issues that can arise by doing this on a VPS?
I ask because I know of stories of law enforcement sending inquiries to owners of, say, exit nodes requiring certain information about given traffic. I don't know if this happens for middle-nodes (or whatever they're called).
Moreover, are there any issues with associating a node to, you know, your name and billing information?
I don't know much about this, and although I could look it up, I think that my questions - and your respective answers or those of others - might do some public service of information sharing here.
