No, I use commercial fonts with my own TFM/VF files.

What I meant above is that I recently bought a sans serif variable font,
that I would like to substitute for cms, but I don't know how to create
TFM files for that. So, I require luatex if I want to use it.

Apart from that I only expect minor differences, mainly because I don't
have to split each font into several pieces. So I don't lose kerning
information between glyphs from different pieces. Also TFM metrics
support only a small number of different widths/heights. So the real
metrics have to be rounded when generating TFM files.
