Geoconversion itself is quite easy with FSET and will no doubt get easier when ipacs updates the tools to do auto inf2tfw, better error diagnostics and maybe add features to make adjacent and overlaid sceneries easier to do.
So, let's assume that side of the job becomes simple enough that it is no longer an obstacle to 90% of people, which would be handy due to the licencing issues. That leaves just one thing (I think) which is time consuming, and that is water/coast masking. Could there be a way that we can re-use and share these PNG files which geoconvert outputs as an input to the geoconvert process? That way we could co-ordinate sharing the work of creating coastline masks and a handful of us could do the whole of the UK say and store the mask files in a download area.
Just the musings of a 4am insomniac....
