did you get any feedback on this? Are you interested in providing some /
all of that data for a nice benchmark at FOSS4G? If so, please holler on
this list and hopefully the teams will start to move a bit. I am sort of
getting a bit nervous that we will not have a benchmark at all.

We have an offer from Ordnance Survey to help us use their OS OpenSpace.
Michael Smith offered to provide for hardware. So neither tin is a
problem nor lack of data, just people starting to set up their machines.
If you want to participate please read this and add yourself:

Maybe somebody feels like herding cats? Please feel free. Better even,
please feel obliged. Note that I am off grid [0] from 5 to 20 August and
if I don't answer it does by no means mean that I am not interested.

Similar issue with the proposed Desktop Benchmark. Neither gvSIG nor
QGIS seems to be all that keen on doing something. Maybe CadCorp is
interested - as sole competitor they would instantly also be the winner.
Hint hint... :-)
