I guess a magsafe ethernet connector would have too much noise (owing to poor quality connection) to provide decently high bandwidth.
I don't see why a magsafe connection would be any more or less noisy than an rj45. They both follow the same principle: spring tension to hold the contacts together. The main issues with magsafe are: 1. You can't have very many pins before the power of the magnet necessary to overcome the spring tension approaches the ridiculous. 2. Past about two magsafe connections to a machine, cable tangle will cause them to frequently pull loose. 3. RJ45 implements spring tension the simple and cheap way. Magsafe does it the complicated and expensive way. You can pretty much forget about field termination. Want some entertainment?
