Wrong.

Virtual fonts have nothing to do with TeX. They are a way
of combining several .tfm's into one tfm file, so that TeX
can handle it as one font. By definition, TeX knows
nothing of virtual fonts. The problem is one for the
device driver, which has to gather the characters from
this supposedly one font out of several font files.

Read the article in TUGboat a while back.
