One more possible thing:

signal noMoreOnlineUsage()
// signal that get's emitted if the last explicit online using app unregist=
ers
// so kppp or kisdn could autodisconnect

At least I would find this useful for my online behaviour sometimes (dial i=
n,=20
start surfing, select some interesting material and start downloading it,=20
wait for finished downloads, disconnect). With the feature proposed one cou=
ld=20
start the downloads, tell kppp to disconnect on no further explicit online=
=20
usage and relaxedly go to supper. (Why don't I simply trust the "Disconnect=
=20
on silence" feature? Those OnOccasion apps might come into the game.)
