Great so I will continue to work on this.

Yes suspend/resume would make more sense, I've decided to go with
start/stop only for this "demonstration" as the WebMiner has no
suspend/resume at the moment.
The dataengine will later support both, but only suspend/resume will
be available as buttons in the applet.

I guess for the email/akonadi part this is working. I have currently
no emails in akonadi to test this.
For the file watcher/indexer I'll work on some patches when I have the
time to extend the dbus information.

Ha, yeah the qml part isn't really beautiful but I'll do a proper
layout once the background stuff is working completely.

I like to put the dataengine/service into:
kde-workspace/plasma/generic/dataengines/nepomukservice

and the applet into:
kde-workspace/plasma/generic/applets/nepomukcontroller

This is where the battery, devicenotifier and all other stuff is located too.
