Likewise here -- we have some work-arounds, but that's exactly what they 
are. Dateline issues mainly -- but I know I've seen issues with polar 
regions as well. OTH our engineers haven't conjured up suggestions for 
functions that haven't already been made, and none of those seem to be a 
high priority. (Is there geld for this work is another question ... our 
new corporate owners have more need for dateline / polar areas than did 
our core business at GlobeXplorer, which was more US/Euro-centric (but 
there are US possessions and parts of Alaska that do cross the dateline) 
but I also have no idea if they are open to funding OS. I can always ask 
I guess, if there's enough other interest.
