Hi Everyone,
my company developed a navigation software , We're actualy using a 
professional vendor map ,  in this 4 years of develop we change our 
binary format every 3/4 month , because the problem is that the embedded 
device , normaly ARM 10 based have a small resurce , small ram memory , 
small flash SD card and are not so fast to access the data. So our binay 
data is optimized for fast access of data for routing and rendering 
I think that is not so simple define a standard binary format because 
every customer are developing their library to access the data , doing 
the routing , rendering ecc.
So I think that is better working on standardization of  map data  , 
quality of the data and routing specification of data.
I don't thinks that a binary data is so interesting for developer that 
are working on mobile application. Infact normaly they working on 
different kind of map Teleatlas ,Navtech ... and also OSM and develop 
some plugin importer for their platform. Actualy our company use shape 
file as exchange format and are woring to implement an importer for OSM 
0.5 data.
Best Regards
Roberto Navoni
