Sounds good.

When I made my proposal, I didn't realize that the IGates could handle non-aprs
packets.  I also didn't see a way to add a timestamp to a packet to handle
packets later for people who don't have full time internet connectivity. 
However, other people have come up with suggestions for extending the
current protocol that might work. 

When I have a chance I may take a look at what data is out there and see what I
can do with it.
