Tell me, when your user has downloaded an app and wants to relink it with their custom version of Boden, how do they proceed?
(VLC is an example of a well-known program that relicensed to LGPL and now is available in the app store, so clearly it is possible)
(There are plenty of App Store apps with LGPL code in them. The question is, should they be there? And VLC is not a good example, since presumably, I don't know - but I think all of it is LGPL or in any case, open source. The user can rebuild all of VLC in that example. The situation with Boden is going to be that a an app, probably proprietary, has a Boden library in it.)
Others have pointed out how it could work with closed source apps. It's a bit more complicated, but it certainly is possible.
