Don't forget that there is another -- sometimes even more irritating -- limitation:

      3.	names of METAFONT font files must be unique withing texmf/fonts.

This currently prevents me from installing some non-standard cm variants 
that come with modified versions of punct.mf, romanl.mf, romanu.mf.
(This real world example is for the cmttss{c,lc,bc} fonts by Art Ogawa.)
Installing them below texmf/fonts/source/public/cmttss would affect the 
standard cm fonts if cmttss/*.mf is found before cm/*.mf during searching.

I don't have a solution to offer for this, but it might be a good idea
to point out this restriction on the uniqueness of file names.

Cheers,
Ulrik.
