Alright, that would explain it.

From the point of view of ConTeXt/LuaTeX use, there's no need for the fonts to be installed in Windows; you just need to have all the files somewhere that OSFONTDIR (or the default font paths) will point. The font outlines will be embedded into the PDF by default, so the OS doesn't need to have access to them.

The point I was trying to make here was that on my system I _needed_ to 
install the fonts in Windows first. Otherwise mtxrun wouldn't find them, 
no matter where the afm files were. This is maybe because of the 
directory structure, but I have no idea, especially as somewhere it was 
stated that I should just "put the directory there".

I have the following:
texmf-fonts \ fonts \ rsfs \ *.mf
texmf-fonts \ fonts \ rsfs \ type1 \ *.pfb
texmf-fonts \ fonts \ rsfs \ type1 \ afm \ *.afm
texmf-fonts \ fonts \ rsfs \ type1 \ map \ *.map
texmf-fonts \ fonts \ rsfs \ type1 \ pfm \ *.pfm

mtxrun finds the pfb (pfm) in C:\Windows\Fonts and the afm files here. 
But it doesn't look for the pfb (pfm) in texmf-fonts... Is this because 
of the "legacy" issue? It's pretty inconvenient.

I'll keep in mind that the type1 fonts are obsolete. I just thought it 
would be a nice idea to try "getting some font" with the rsfs first, as 
there were "full examples" (which do not work here for some reason) on 
the mailing list.

Thanks for the help,
Stefan.
