If you can knock something of that quality up so quickly, then theres no reason why this cant go 'live'.
A list of things that need to be added to the map:
Areas to park
Trail notes (like you have already)
Facilities (shops, public loos etc)
Any 'special local knowledge' notes (ie the trail continues over the road behind house no.3)
Basically, anything that can help someone who isnt familiar with the area that wants to follow the map and enjoy the ride.
