This comes from the long and actually relatively old now Transmission forum:

Interesting. Anybody has in mind to work on bringing Bittorrent to Fremantle?

A lightweight client very good in just a few use cases: responding to clicks in web pages, perhaps making search easy, perhaps making easy hosting seeds...

Very clever with power management and helping users to make the most of their wlan/data connections without making expensive mistakes.

Absolutely simple in the UI (yes, finger-friendly). Click link in web page, dialog appears, press ok. Search box, browser results, select. List of seeds with checkboxes for shareable/not shareable. Clear dialogs to define bandwith to share, policy for data connection, option for operate only when wlan is active and device is charging (e.g. while you sleep).

Oh, and imagine that lovely and cute desktop widget showing the % of the files you are downloading and giving access to the app itself.

What else? And how far would this be from what is available for the desktop or other mobile devices?

If someone is working in a similar line please share your thoughts. If you are good and determined you could even have a chance joining us in Copenhagen. There is also a GSoC aiming to integrate a Bittorrent plugin in Canola, perhaps that work could be reused? Nothing against Canola but it is possible that a lightweight Bittorrent client can have a demand in its own.
