calculating routes on the empeg is verrryy slow

I wasn't talking about calculating routes on the empeg. I was saying: still use StreetAtlas to calculate the routes and send only the route file into the empeg. Just like now. But skip the loopback-through-two-more-Windows-programs trick, and instead make the empeg itself emulate a Garmin rather than have another Windows program emulating the Garmin. Just enough to grab the route file. At that point, the empeg wouldn't have to calculate anything, it would just do a file format translation.
