how much public api said libraries would need to be used by something? i still 
think a dataengine with a couple of services would be nice there (it would be 
nice to be able to dial from a random contact list plasmoid, even if would 
pose the problem that maybe only some authorized plasmoids should be able to 
do so...)

yeah, in this case a c++ approach is good since otherwise it would export too 
many things that would become "almost" public api (right now for instance is 
possible for anyone to import and use random pieces of kmail... not sure is a 
desiderable thing, but this is another of my pet peeves with qml ;p)

yup, sure, having something that works as an experiment is always good, then 
let's engineer it a bit :)

yeah, not even to me actually ;)

my old phone with a 176x208 pixels display can fit it :p

good :)
