The iridium module seems impossible to get in the US, at least if you believe their website. I sent off an email to Globalstar sales and hopefully they will get back to me soon. If you are correct and the price is several hundred bucks for the modules then it's a nonstarter for me but if it's priced similarly to a GPS module in the $50-100 region I can see it being worth while. At several hundred bucks I'd need to discount the hardware and make up that money on a monthly subscription. That would require bookkeeping... yuck!
