Take a look at any 'free' (open source) license. If you're not changing the code you are free to distribute, just keep the license with it. Repackaging something for maemo and keeping to those steps is 100% legally ok. Take a look at pandora. Guys are repackaging things like (http://boards.openpandora.org/index....in-first-post/) where license clearly states:

You may freely use, modify, and distribute both the FB Alpha source code and binary, however the following restrictions apply to the FB Alpha original material (see below for a list of libraries with differing licenses, please consult their respective documentation for more information):

* You may not sell, lease, rent or otherwise seek to gain monetary profit from FB Alpha;
* You must make public any changes you make to the source code;
* You must include, verbatim, the full text of this license...

So, pandora guys are explicitly breaking it making only binaries of modified code available. If they got the code out we would have the same goodies, but nevermind the license. Maemo community at least respects authors' wishes.
