The X client (server, actually -- it 'serves' the display to the 'client'
program.  Quite confusing.) doesn't need a font server.  We don't use the X
font system at all, only font-config.  Since X font servers cannot give us
the outlines of the fonts nor the font data itself, we cannot use that for
rendering PostScript.  So to ensure fonts being the same across the board,
we just ask FT2 for fonts, and it finds them via font-config.

I know this is going to be a problem for systems that don't have fonts on
the client computers, but it's not like it's hard to install fonts (once
you don't have to install X server as well).  I've been considering
packaging a minimum set of fonts with Dia, but that's really a packager
issue.

font-config (/etc/fonts/fonts.conf) is what you want to look for.  I'm not
sure what it'd look like for an X client, but if you can just have it point
at some dirs with fonts, you should be ok.  See fontconfig(3), which has a
section with a User configuration file example.
