Dave,
Can you elaborate a bit on the implications of the various types no
longer being subclasses of GEOMETRY? What does this buy us?
I like the idea of keeping the data in WKB within the database, though I
also don't know the implications of this. Where would you store the
SRID for each geometry?
Best regards,
