Before I buy Hotspots, please let me know:
1. Can I center the map on the location of a visitor (unregistered user in Jomsocial) and show active spots of other registered users around that visitor?.
2. Can I display an icon that represents the position of the visitor on the map?.
3. Can I have markers clustering for maps with large amount of markers? (multiple Jomsocial registered users in the same point of the map).
4. I currently use another component for Joomla! that does not focus correctly on the map position of the visitor .
With "HTML5 Geolocation" centers the map at least 3 kilometers away from the correct position of the visitor.
With "IP address location" (through "hostip.info "
centers the position of some visitors in the middle of the ocean. 
¿Hotspots also have these problems?.
Thanks a lot for your time.
