For a first test, I have submitted a request for opening the Sharing services framework https://bugs.maemo.org/show_bug.cgi?id=11128 Bug 11128: Opening the source for Sharing services framework I have heard from different people who have tried to implement extensions for this important aspect of the Maemo system for a while and recently albanc has gone to extreme lengths to actually implement a new button on the sharing dialog. This kind of hacking that he did (as amazing as it is) should be totally unnecessary if the code was open. People have at different times requested alterations and minor tweaks to this but have not had the skills. Have a read of albans blog about how he did it in monorail http://alban.apinc.org/blog/2010/07/...-on-your-n900/ you would be surprised at how much hard work adding one simple button would be! Yet again, this shows open source will always find a way to do things, but I would like to make it as easy as possible for others.
