hmm, this is the part I'll try to skip

right, that's my dream too.
I'm not sure but I think that Tim Schaub has already inserted a OWS 
parser indipendent from OLON. I have to check OL's Trac.
If not we can temporally use my OWS class to extend OL.

I would like to talk about the directories structure.
- how to include OL?
- downloading last published version and creating a dir structure like this?
- what should happen when a new release of OL is published?
- how to deal with the huge amount of functions that OL offers?
- should we provide the FULL compiled (aka escaped) version? or the 
entire code of the project? (thinking to debuggers)
- should we just provide 2-3 different flavored compiled files (minimal, 
all-layers, vectorial-drawing, whatever...)?

more questions will come soon
