While we are on the subject, of a "Perl browser plugin" , like the libjavaplugin_oji.so in our browser's plugin directory; what has stopped the Perl developers from doing this? From my limited understanding, the java plugin is just a java interpreter with the functions which pose a security risk removed, leaving only simple computational and display functions, and which limits display in the parent's (browser's) allocated window.
When I build Perl, I see the mini and micro Perl interpreters, which are limited versions. Would it be that hard to modify those to be a secure browser plugin? Then maybe add a chopped-down Tk or Gtk2 display engine to it? Now I wish I studied c in more depth. :-)
