I would try a cutting from a relatively easy growing vine as a start. The roots and dormant node will grow with about the same speed, so it will have a good chance to establish. Also this way if it didn't work out you wouldn't loose a plant just one cutting.
Somewhere online there is a japanese Nep growers website which has tons of pics of many of his plants (seedling to mature) growing mounted on dead moss covered branches in his greenhouse in the manner I described. Unfortunately I can't find the link on my favorite places right now.
Just look up nepenthes on google and check the sites that end with ".jp"... it's one of them! [img]http://www.**********.com/iB_html/non-cgi/emoticons/laugh.gif[/img]
