By "etc." do you mean all the tfm files under

/usr/share/texmf/fonts/tfm/public/tx/ ?

I believe an important step towards loading /any/ tfm-based font is to
write a function that calculates the basename of both the .tfm file and
the .*pk file.  For most fonts,

<family><size>.tfm and <family><size>.<dpi>pk

does work.  However, in the case of txexa and all the other txfonts,
this format does not work.  The files must be of the form

<family>.tfm and <family>.<dpi>pk

Consequently, something like

string CalcFontBaseName (string family, string size)
  {
  if ("txexa" == family)
    return family ;
  else if ("txsyb" == family)
    return family ;
  else if ("txbttsc" == family)
    return family ;
  ...
  else if ("some_other_font_with_no_size_in_the_file_name" == family)
    return family ;
  ...
  else
    return family * size ;
  }

would solve these problems.

I have looked at the txfonts, and many do not follow the
<family><size>.tfm convention.

So far, TeXmacs can handle Type I fonts, correct ?  That is, it can
handle any font that has a .tfm file, and a corresponding .pfb file,
because one can call mktexpk on it.

I don't yet know how, if, one can create .pk files from the virtual
fonts in txfonts.
