the email's subject contained the necessary hints.  ;-)

What exactly are you looking for ("middleware" is a pretty broad term) ? An 
application that can send GPS data through the network ?

Yes, batman can help you "extending" the network. But the biggest troublemaker 
will be the wifi driver because adhoc mode isn't that well supported. 99% of 
the users want infrastructure mode, therefore developers work on that first. 
Adhoc mode comes later (if at all), is often buggy and not well tested. The 
wifi communities get around this issue by focussing on hardware which either 
comes with an open driver (e.g. atheros chips) or have a working adhoc mode 
implementation. Depending on how much freedom of hardware choice you have I'd 
suggest you carefully pick your wifi chips.

Please, share the results of these tests with us. Even if you don't choose 
batman we would be very interested to find out what we can improve.  :-)
