p.s. a quick reminder that all messages sent and recieved ... are to
be considered public information... :)
So if you forget to put a note 'off-list' message, you might as well
be chatting in a coffee shop with a microphone attached to you. :)
... and for OpenSource mapping, this is not a bad thing, as it allows
for (literally) countless number of people to read this message, and
to try to help solve the problem. (of seemlessly integrating multiple
datasets in an OpenSource geo-database with no restrictions of use,
and benifits everyone collectivelly)
.... regardless of the silly OSM licence debate.
.... its a good thing that there is little competition in this field
of OpenSource mapping, although our collective view of what
'opensource' and 'mapping' means, is about as different as everyone
reading these words.
cheers,
sam
