Hmmmm I don't see why we couldn't add routing algorithms into GEOS - it 
seems a bit redundant having both Boost and GEOS linked into the same 
executable.

About liblwgeom, it would be interesting to spin it out into a separate 
library that could be used by Ingres/PostgreSQL/whatever so that all of 
the basic SQL-MM functions could be made available to other software. It 
would also standardise the internal representation of geometries which 
is also a good thing.

Paul: in terms of slugging data between C and C++, don't worry - just 
pass pointers to arrays of doubles between the two and magic will happen.


ATB,

Mark.
