Thought about this a bit. How about we add an entry to the applet's .desktop file, 
called URLPatterns (or something like this). This is orthogonal to the mimetypes the 
applet supports. We could then make containment list the applets that have one of the 
globs matching the URL.

For the email applet to be able to recognize akonadi URLs. this would look like (in 
it's plugin .desktop file):

X-Plasma-URLPattern=akonadi:/*

Other usecases are specific protocols, think of man:/ adding a webview pointing at 
the manpage. Selkie could use this to decide wether or not to offer a Selkie Plasmoid 
for a given URL (for example X-Plasma-URLPattern=http://gitorious for a gitorious 
selkie), I'm sure you can come up with more use cases...

Is this something I should pursue? It sounds simple enough ...
