Jan, are you looking to integrating this into gpsapp more tightly

I downloaded it, but haven't had time to try, or even look at how source was integrated. I did look at the roadmap sources to see if it is using a nifty encoding scheme, but it is pretty simple. I'm probably just going to see how it is developing for now.

(2a) The way routes are drawn would have to be changed considerably to get the crawling ants effect. Because it depends on the scale and we can't treat each route segment independently.

(2g) Yeah, transparency never was a problem with the simple route display. But clearing the area underneath the popup is pretty trivial.

It definitely has potential.
