For the first time I met developer who is so fast in issue solving. Using plugin for a week and don't want to use any else stuff.
I had a problem with displaying markers from all 307 posts at mashup map.
In a day the problem was solved and I was e-mailed with new hot version) It's a greate support!
I beleave this plugin would beat all other plugins and be the most popular. With this author it is very possible.
And good luck in US!
