Hi,
You should fine the forest 2.2 beta has introduced a more descriptive naming scheme for instances. The format is forestName_objectName_###, hopefully this will be useful for your requirements. Thanks for the kinds words about the plugins, I'll make sure it's passed on to the rest of the team.
It's interesting to hear about RailClone being used in game dev - if you ever have any examples you can share we'd love to see them.
Many thanks,
Paul
