That's cool. It should have been like this from the start :-) Having to 
start our own listener for communicating with UNO has been problematic 
from the start, mostly because it's not very stable.

The differences I see:

  - Remote conversions (only with shared storage)
  - No need to know the internal filter names
  - Possibility to provide filter options to filters
  - Possibility to apply styles/formats (from templates or other
      documents) during conversion
  - Output to stdout

I am not a C programmer, so I don't think I can be very useful.
