If lifts were invented now

I pressed the wrong button in the lift this morning, and realised that there was no undo button. That would be unthinkable in any interface designed today, but lift controls are virtually unchanged since the 30s or whenever they dispensed with lift attendants operating levers.
If lifts were designed now they would have:
• a cancel button
• executive prioritise button (takes boss to boardroom penthouse, then goes back down for the rest)
• themed chat suggestion display (weather, cricket score, office gossip)
• personal login with preprogrammable functions (go to my floor, visit boss, go to staff restaurant)
• replay function (enjoyed that trip to floor 7 - let's go back down and try it again)
• slow speed function (for when that elevator pitch is taking too long)
• wireless network so you don't lose a moment of precious work time
• personalised follow-me musak
• mood lighting for those brief encounters
• virus checker.
