Hi,
I'm in love with RC and I've made a live data viewer inside my site:
http://granturismo-italia.it/
You can send live data by a simple upload form (only in .kml format) and I will display them immediately on a gmap on your profile page.
To upload file you simply have to registrer (it is free of charge) .
The site is brand new and for the moment it is only in italian, but I will be glade to translate all the necessary.
Example
enjoy
