I don't have a better one off the top of my head.

Somewhere there has to be a pattern and replacement for
each acronym, which to me does imply that there's a lot of
additional pattern matching taking place.  I don't have any 
immediate ideas for improving this.

One thing you could try is to do something similar to the
way the InterMap code works, which combines all of the keys into
a single pattern to be matched.  For example:

    Markup('acronym', 'inline',
      '/\\b(html|xml|http|tcpip|dhcp|smtp|pop)\\b/e',
      "Acronym(PSS('$1'))");
