Okay, so we need a voting for the Multi-Platform Award,
we'll suggest to target the maemo-ish platforms first,
and we'll take both amount and quality into consideration.

Good idea, but would make the election process more difficult to understand.

How about that:
all apps which are available for multiple platforms will automatically be part of the multi-platform award voting.
In the voting process, we not only show the name of the app and link to it, but also show the amount of platforms it is available for so the voter can take this into consideration.
Of course not everyone would be able to test a multi-platform app on every platform it is available for...
But is that needed?
The idea of adding a voting process is just to filter out the low-quality apps from the high-quality ones, so testing is only needed on one platform.

The community participating in organizing the coding competition would just have to make sure that the app really runs on the advertised platforms.
I could test on N810, N900 (maemo5 and nemo), N950, BB10 dev alpha, Symbian, Android...
I'm sure we'd find iOS users if needed...
