Hi Nicola
I guess I can help you write this up as a proposal, and I will review as I
go (and vote!). Just quickly does this proposal require any changes to the
geotools api (and thus documentation?).
There was a lot of enthusiasm for this work at the foss4gna bird of feather
session, and it sounds like this work will be amazing.
