I am interested in trying MM with nautical charts, has anyone done this?

What I have in mind is the following:

NOAA in the US publish free very detailed raster charts of US waters in 'BSB' format. (Many other countries publish in this format too, but they are not free). 'BSB' format uses a .kap image file - which looks like it can be converted to, for example, ( a huge) .tiff which can ultimately be processed by mapcruncher (http://research.microsoft.com/mapcruncher/) into a format that can be used by MM.

I have seen various posts (mostly by kempja) about making your own maps from images. Did these ever come to fruition?

FWIW. Here is a site (http://www.zoomatron.com) that has done something along these lines, only he has overlaid NOAA'a charts on to top Virtual Earth maps.
