What about to let the winner of each category decide?

This was so far a fair competition with developers helping each other and pay tribute to other projects.

We could take a modified option 1. Spread the donations to place 1., 2. and 3. - but let the winner of each category decide, would you take the small Bounty from the community or is the Trip sponsored by Nokia or a shiny new N900 enought for you and give the money (it's already not soooo much) to place 2., 3. and 4. as a booby prize to appreciate their work and to motivate them to continue their projects.
