FWI--- For those interested, It is possible now to create a crude keynote system in Archicad using Python -- and without not too much effort. It certainly won't compete with CadImage but acceptable.
Attached is a Demo video for any interested.

Eventually,I expect to see a keynote system in Archicad and if/when we do, i would like o see the same capabilities as mentioned in this video. Also please expand Python so that we could address and create labels with Python with line pointers. Archicad has some excellent ones that would be ideal to be used with Keynotes.
