Gee,
You can always perform a "Jarre stunt" and shoot a video of yourself miming at the PC Keyboard - make sure you "write" damn super fast and keys light up (no need for characters printed on'em though) - and with a pre-made site (by you, of course, *ahem*) in the monitor (big) in front of you...
Some IT engineer can do the solo by fine tuning some Cisco gear located before the server...
Ask your cat to turn it all on, for the show... and bang, instant fireworks, so don't go doing it in the Forbidden City or make sure it's not going to rain (er... diluvian rain, I mean).
Kind Regards,
AMR
