Yes, but I was really just suggesting dispensing with a filesystem and writing 
to it in a long stream.

Bah. You have no sense of adventure.

http://www.globalsat.co.uk/product_em406.htm is the sort of thing I was 
considering. They sell USB dongles with them & a USB-serial converter in them 
for £50, so the OEM module can't be too much - If the worst comes to the 
worst, buy a USB dongle and crack it open.

I concur that in reality you'd only get very minor advantages over the 
navigps, those being very slightly lower cost, and a sirf III rather than a 
sirf II/unknown. And you'd get a lot of disadvantages over a navigps.
