Hi Michael,
you can try Postgis. There is a function that fit the points into the
closest geometry chosen, once you have this layer fitted, maybe you
could try to calculate the distance between the points that have same
ID, is not a direct solution, but maybe could help.

Cheers!

I am trying to calculate the distance from points to vector lines.
There are various ways of doing this when there are relatively few
points and lines but my datset has 200,000 points and a large network
of vector lines and none of the tools I have tried in qgis seem to get
anywhere. I have also tried converting the lines to raster but not
clear what resolution to use and with high resolution the problem also
seems to be that it takes forever to do the calculation. If the tools
gave an indication as to how long it is likely to take that would be a
help e.g. 12 hours but waiting 12 hours on the chance that somethign
might happen and still nothing is very frustrating.
