Hey Sanjiv,
There is no information about that since there is no such functionality in Hotspots for this.
Hotspots can make the read more link to point to a k2 entry. But it cannot automatically show the k2 items on the hotspots map. Lately I've been contacted by a lot of users who use k2 with custom fields that store the lat & lng values. I need to find out how one makes such a config and we could then eventually write a plugin to automatically insert the k2 entries into hotspot. It's on the todo list, but first we have to get 4.0 out.
Regards,
Daniel
