I'm not a "viking developer", but my $0.02: it sounds a little too specialized, but having a branch isn't really that great either replaying a 'race' is really 'replaying a gpx trace' and is generally applicable to people who want to see what happened, whether its for a sailboat race or something else. So perhaps this could be a feature of the trackwaypoint layer, not a special layer. not sure what 'add marks' means, but that's really just a general case of waypoints and "off-road navigation" to the next waypoint in a route VMG could perhaps be shown in trackwaypoint layer after a route is defined somehow so basically my advice is to not write a layer to do everything you want, but to figure out how to write a number of smaller features that together meet your needs but are individually usable.
