Doesn't the application need to be compiled to 'receive' those mime file/open commands.

I thought/think that in order for hildon filemanager to open a mime type , that target application would need to code a osso callback function like :
http://maemo.org/api_refs/3.0/liboss..._MIME.html#ga1

So all the apps being ported which only work via command line would have to be modified to get mime parameters/commands.

Is there some way i can have file manager launch a non-hildonized application and pass that filename over the command line?
