Known Problem

Please note there is an issue with jquery 1.4.4/1.5.1 + rails ujs driver + google maps API v3: clicking on markers, or using other 'live' event triggers on the page will result in a critical error on IE < 9.

There is a workaround available. For more information, please see this discussion http://stackoverflow.com/questions/5221787.

Json creation

You could see in the code that I'm almost recreating the wheel, rewriting some kind of to_json method.

Indeed, I did a benchmark with 1000 objects:

Benchmark.bm do |x|
   x.report("builtin json:")   { User.all.to_gmaps4rails2 }
   x.report("custom_method:")   { User.all.to_gmaps4rails }
end
                  user     system      total        real
builtin json:  0.780000   0.020000   0.800000 (  0.817267)
custom method: 0.460000   0.020000   0.480000 (  0.502094)

So I kept my own json creation method.
