If you want to focus other people on your problem,
why not point them to some free public data that
illustrates the issues?

Pick a Canadian NTS mapsheet, and give them the
URIs to:
- the CanMatrix product (a raster image made by
   scanning the front of the paper Canadian topo maps)
- the CanVec Canadian National Topographic Database
   data that you want to use to produce 'the same' map

You and I both know that the result of using that
CanVec data won't exactly be the same as the CanMatrix
product, but at least it will be a concrete example
that people can use to 'get their hands dirty'.
If people think they have a solution, they can even
buy the actual paper map, and print their map made
from the vector data, at the same size, and compare.
