So I say dataEngine("contacts") --or "kdepim". Is there such a thing working?

What do I do with the "dummy" engine?

I mouse movement engine which yields Q...MouseEvent object of some kind should
contain any mouse-buttons, coordinates, and hopefully or additionally the
window or object currently owning the mouse (which should not be the applet).

I need more documentation on krunner. However, the queries are not always
running. If I want to do it, there is a keyboard shortcut like ALT/click to
trigger the query.

I never used kisa to correct spelling in a doc since that program already had
spell-checking. Typing into a console editor like vi can use it, also syntax
checking, etc. I never tried it for insertion into target window because this
was not particularly well-behaved. Just took the hint and selected if I needed
it. Translations would simple display as well.

Yes. The windows applet from answers.com uses a proprietary, patented method
NOT relying on OCR. Babylon's applet uses OCR. (My familiarity with this stuff
is a number of years old.)
I could say if the owning window has text, get that. If not, go through OCR on
some region. In the end, probably simplest to select as you said and either
pull off the clipboard or drag and drop to the applet. These both contain
mime-type info which can be used in interpreting the selection.
The instant information on click is quite nifty, however. (and is built into
some websites)
