I have been reading a fascinating book about nautical charts.   It turns out that there are many pitfalls in using GPS navigation that result from the translation processes that take place between the original survey data (some of it quite old) and the GPS devices.  It would be great to use a Bug to store a history of lat longs and depth soundings each time one goes out with a boat.  The data from many bugs could then be used to improve the accuracy of existing charts. 

But even before getting quite so ambitious, I would simply like to be able to easily record all the data from my instruments and plot them afterwards.  It is already possible to do this by connecting a laptop up to the serial port of the instrument data hub (via the NMEA standard), but a bug would provide a much better form factor (and lower price point), especially if one could figure out a way to easily tap into the wireless network among the instruments.
