hehe.. no, none yet ... reason i want to talk about with Marco is this will 
impact our devel efforts elsewhere in the plasma-mobile code, so we would need 
to factor any changes in there.

and this really seems like the sort of thing that ought to be available in the 
Plasma Components in kde-runtime so that everyone can use it (and hack on it) 
without making copies :)

imho, probably KF5 because:

a) we want KF5 sooner rather than later, so efforts should focus there.[1]
b) KDirModel is such a key component with a high complexity and few people who 
know it very well; so it needs lots of testing, and 5.0 would be a better 
target for that kind of development imho
c) it will give us something to market about 5.0 -> SO MUCH FASTER / MORE 
FLUID DIRECTORY LISTINGS (that's mostly, but only mostly, tongue-in-cheek)

[1] as an aside: we've re-focused effort on libplasma2 in KF5. the new QML 
based containment stuff being worked on has been moved to libplasma2-only and i 
expect other such development in Plasma to continue that way. we're also 
expecting / planning Plasma Active 5 to be focused on moving to Qt5 + KF5.
