Idea for Ḡchange marketplace delivery service
To help delivery process in gchange, here is an idea:
When buyer and seller are OK (but too far for delivery) a special "Delivery Deal" would be created containing buyer/seller + object volume and mass + actual and desired localisation + Ḡ1 price offer (from buyer).
For "Delivery Service". A special map will allow to filter objects desired roads "to and from" the searched location. Then "Delivery Deals" can be accepted and done...
For that information system to run well, it needs to be able to quickly contact people: email or sms notification service feature could help ;)
