Nice to know I am not the only one with this idea :-)

The system is not only for traffic navigation, the base of the system
and the reason for using a Symbol PPT 8800 is that we scan (BARCODES)
all packages that we transport for our costumers. The system is going to
run some home made route-planning algorisms (based on the data from the
barcodes) on the road and then uploads these to the primary server using
the GPRS card. Then the primary server plans the total route of the
package. Trust me it is a pretty complex system. :-)

The cool thing about the Soekris is the power needs, size and the large
amount of connects. We are a small company but all system are tailor
made for the costumers that say, I still have to have a based system
that all cars must have.

The Symbol 8800 will still run WinCE do to the vendor's demand of
support and repair.
