Simon Great, just a complementing comment.What I mean is that those examples
shows in a good way that the transparancy open source gives, means a lot in
itself.
It gives the possibility of new users to contribute with ideas from looking at
the code and it makes it easier for postgresql-postgis to get a good
interaction. As I imagine the road from a problem in postgis to a solution i
postgresql would have been quite long and windling in a closed source
environment where Paul and Tom would have to hide their codes from each other,
only discussing the API:s. In that case Oracle would have a great point in
controling the whole chain. But that benefit is not that clear when comparing
to an open source system chain. I guess this is all worn out arguments in the
open source world, but important to remember I think. The open source in it
self gives a strength to the system and contributes to a more flexible and
exciting development (development in a wider perspective). /Nicklas
