Thank you, this seems to be the most viable solution. I'm going to talk to them this afternoon for specific information.
It's a little different since I want to use it like a GPS with maps already loaded instead of WiFi access on the fly. I intend to purchase a device specifically geared to accommodate this application.
Appreciate everyone's imput
I am one of the Gaia GPS developers (Andrew), and I'm always happy to answer questions. We just did a big Android release, and we have another one coming up for Christmas!
I am hoping to get feedback about how we can make GaiaCloud sharing better for geocaching, in particular.
