Hey Andrey!
What's up with that plugin? Did you manage to write it?
I've actually refactored a big part of the code for hotspots 3 and we have now the possibility to create links to sobiPro, k2 and any component out there for which we create a plugin. (I've also corrected the import function to now import from sobiPro instead of sobi2)
Actually I would like to add a sobiPro plugin that would add sobipro entry to the hotspots database. Did you make any progress on this?
If you want to test the development version:

(DON'T USE ON PRODUCTION SITES - IT IS NOT READY YET)
