[Loadstone] Feature wishes, re-issue

A gps emulator feature would reverse the program, turning it from a client 
into a server. This would be a large complex bit of code with only corner 
case usage. This would be the absolute worst way to transfer points between 
other loadstone users, it would kill the point duplicate checking if the 
data were uploaded to point share. You may be able to get other navigation 
programs to give you data this way but that's a pretty dirty hack. Depending 
on the program that may be a violation of the license agreement. If so and 
that data ends up on point share then we may be in trouble for that as well.
The only somewhat interesting use you mention is to use this as a bluetooth 
relay so multiple phones could use the receiver. An interesting idea but 
given the bugs with the various bluetooth implementations getting this to 
work right would probably be a nightmare. Again thoe, how often would this 
actually be used? It's probably not common for users to carry multiple 
phones with multiple navigation solutions installed on them.
For the use you're trying to make this do you'd probably be better off to 
make your emulator take a loadstone export file and then do all the 
processing you want on the pc. This would also cover the reverse point 
sorting as well. I doubt you'd do this processing on the road but if so then 
a laptop would be the way to go.
