This google maps implimentation of the IRLP connection map is very very much alpha / experimental at the moment.

Only connections to main reflector channels (blue) and point-to-point links (green) are displayed. There are too many sub-channel connections in use to display. Maybe I'll add a toggle per channel later. In IE the polylines are actually VML vector-based. Hopefully the google map API will add support SVG as they did for Microsoft's VML. I'm rather suprized they didn't support SVG first.
