The interesting bit isn't open source - assuming the policy of keeping maemo.org Extras enabled out-of-the-box is maintained into the future. The interesting bit is, I think, developers who do some open source work and some commercial work.

Would I consider charging 99p for Hermes? Maybe (probably not). Micropayments are fun, but I know I'm not going to make a fortune. However, a little bit of extra cash helps pay for Christmas presents etc.

This thought is moot if the current Nokia approach to maemo.org Extras side-by-side with Ovi, and enabled out-of-the-box, changes. This would be a Bad Thing as Ovi will almostly certainly not have the level of integration and process which has been worked on for so long with things like maemian, autobuilder etc.
