In general you will run out of object RAM long before you run out of
code space, even on a 32K EEPROM. If using the V.6 compiler you may
find an efficient place to keep rarely changing variables is the EEPROM
variable space (internal to the chip EEPROM). Other than that, beyond
the code, the only real use for the external EEPROM is storage of data
and setup information.

To link objects together _is_ the most efficient use of objects, and
the way to get them to run the fastest. Simply defining objects and
using script code is not using the ooPIC to its best abilities. You've
found that oNavcon and oRamp can use the motors to great effect already.
