  That is another option I suppose, one that I'd not considered.

  Right.  This is something that I want to get right the next time
 round.  I'll resist the temptation to write everything now, but
 in short I think that the HTTP-like plaintext protocol was a mistake.

  Partly because of the plaintext nature, and partly because it was
 a pain to work with from the client point of view.

  My intention is to choose a better trasport mechanism which will
 solve both of these problems.  The hard part is making the plugin
 facility seamless - such that remote clients can query available
 methods remotely, and not die horribly when expected remote
 functionality isn't available/enabled.

  My proposed solution is RPC over HTTPS.

  Briefly .. but not significantly.  It might be a good opportunity
 to learn the language a little bit more, but then again it might
 be safer to start with a language I understand - I'm not too sure
 how the plugin-system(s) could be implemented in ruby at my current
 level of understanding.

  Still either way the API provided by the server component should
 be client-language-neutral.
