So, shortly, the maps and the knowledge of the map format is the biggest showstopper at the moment.

Kim, I know this was brought up before and at the time it did not sound like you and smu where heading in the same direction with your respective projects. But, now that the empeg has been EOL'd would you reconsider releasing the work you have done so far for the rest of us to use? It really sounds like you have done 90% of the work already and have a pretty cool system working. If the biggest piece you are missing is the map data maybe somebody else can help with that. I know a lot of people here would be greatful for your help.
