I know what you mean, my last few trips to Washington was timezone hell!

Regina,
Some very good points.
I stopped using the term years ago given that I concentrate on applying
spatial data and functions to solving business problems.
One problem is that the "spatial" industry is dominated by "GIS" vendors
and
practitioners: it isn't easy to find new non-GIS work.
In fact, I think this is one of the problems with FOSS4G technologies:
they are
marketed and sold as specific toolsets in opposition to the vendor
products
but on the same playground.
I have a few examples I can provide you with, just give me a bit of time
to
write them up.
As you going to FOSS4G in Melbourne this month?
regards
Simon
