If we can cut the X server out of the loop then I would hope it would
be just about be fast enough for a demo. Probably not fast enough to
be usable as a real device (unless someone wanted to prove a point :)

Ouch. It should be possible to setup squid on a local machine to proxy
http through to https for twitter. Providing no modification is
required to the client (apart from ensuing it supports a standard
proxy setup) then its arguably not even cheating :)

I wonder if it might also be worth posting updates to a vintage
computing list - I'm pretty sure there are people who would love to
hear their beloved m68k CPUs are still on show :)
