It is quasi-implemented so to speak: In BApplication::InitData() lurks
the line
// TODO: create_app_meta_mime()
for quite some while. It just waits for the function to be implemented,
then it will turn magically into a butterfly... err, no... into the
actual function call. :-)

I wonder how to solve this problem. When walking through the FS the
registrar could as collect the app signatures it finds and remove all
others from the database. But I'm not sure, if this effect is always
desired. Just think of apps on removable media. E.g. a game on CD and
the game states saved on HD -- inserting the CD and double-clicking the
saved game won't work, when the registrar remove the game app before.
Maybe that example is a bit artificial. Mmh, then imagine a network
with applications on a server...
CU, Ingo
