Couldn't sleep, so I got up to try again, and finally got a test
page working at http://www.baconbooks.net/Voynich/meva.htm. If
anyone gets a chance, please test this page and see if you see a
few Voynich characters.
Much as you'd expect, it works fine with Internet Explorer 6.0.2600.0000,
but not with any version of Netscape (I tried 4.08, 4.76, and 6).
Speaking as a part-time web programmer, I'd far prefer to put a link to the
font file on my page than have to rely on MS-only special features.
There is an alternative: you could write a PHP (or Perl, or even
JavaScript) filter to replace any VMS (whether EVA or MEVA) text on a page
with small graphics. Once these had loaded, they'd persist in the
most-recently loaded cache for a good while, so shouldn't slow down
subsequent pages. Just an idea. :-)
