Ah, Sune, guess we were missing each other :) I was talking of currently not 
installed optional things. And not speaking of optional things not existing as 

E.g. imagine someone installing some program over an expensive/slow connection 
(think mobile). She just installs the required things, to keep the needed 
bandwith low. Then hits a feature which is more useful with some optional 
thing X. Ideally the feature's code would be able to offer the action "Trigger 
install of optional thing X to pimp doing Y".

Does this help to understand what I am looking forward to?
