My company builds optimisation services for satellite phone users (ie 
Iridium, Inmarsat, etc), in particular for email, weather and the more 
household kind of needs (we are also Iridium VAD's).  Website is at 
http://www.mailasail.com

Our latest project is an inexpensive hardware router which will try and 
incorporate as much of this acceleration software as possible, and in 
fact in fact you are probably very much part of the target market we are 
trying to design it for?  I would be quite interested to pick your 
brains (perhaps offlist) on some of your experiences using Iridium and 
in particular the kinds of uses you put it to?  Would you consider 
talking a bit more off-list about infrastrutures?  We would be quite 
interested to find beta testers for new equipment?

I'm also kind of surprised, but heartened that you manage to get a 
stable enough ping speed to use chrony over it!  I can only assume that 
this is because the number of satellite hops remains fairly fixed 
between your location and Iridium?  If you look at the way Iridium 
routes most calls you can see that the routing distance can change quite 
considerably over a few tens of minutes - certainly I observe the ping 
speeds to be fairly variable (I'm in the UK)

The OpenPort should bring your costs down significantly, plus you get 
three voice channels.  Should be a very nice upgrade for you.

Please consider getting in touch off-list - would love to chat more 
about your setup!

All the best
