Hey Tony: I see you never heard back from Henry on the first issue (haven’t seen him on the forums in a while, now that I think about it)…but to answer your second question…this MAY be doable but would definitely require some customization on your end.
It might be easier to wait until we’ve got our own geo tagging functionality (which is on the radar but still a ways out) deployed to integrate something like this. You’re welcome to give it a go in the interim, and can ask any questions you may have along the way, but sadly we probably won’t be able to provide much more than attempts to point you in the right direction.
Hope that helps and sorry I couldn’t offer up more. Let us know if you need anything else here.
