Crawling, indexing & ranking
Based on the angle you're presenting, I see no reason to use a .net, not only that, it could be a major PITA and do harm if it got indexed on accident.
Sounds to me like you're over thinking things. If you're really concerned, just use nofollow on the links and you're in the clear and far less effort expended.
