Java ME bittorrent client and mobile operator network compatibility

I'm interested in developing a Java ME BitTorrent client such as MobTorrent to use in a Distance Education/OpenCourseWare suite for feature phones such as Nokia Series 40 phones.

I've done some research into this idea, specifically on whether it would be viable to have feature phone users download ~41MB torrents of audio files through their mobile operator network. I've found that som开发者_运维技巧e mobile operators block torrent ports or ports outside of a very specific range needed for e-mail and web browsing.

So, I was wondering if anyone knows of a way to have the distributed, peer-to-peer file sharing benefits of torrents while not having to deal with blocked ports?

Do I use proxies? Do I figure out a way for torrents to use port 80 (http port)?

I want to use torrents because I need to avoid using dedicated servers, as most OpenCourseWare distributors use. The bandwidth costs of dedicated servers would be too expensive.

Thank you for your time. I appreciate any help that can be provided.
