Google Calendar as external scheduler for DZ???

Just thinking aloud - would using Google Calendar API be a gross overkill or actually a smart idea?

Let me see...

• Unlimited number of zones supported...
• Unlimited number of periods scheduled...
• Arbitrarily flexible scheduling - you want 5+2? We have it. You want 5+1+1? We have it. You want 7-Day? we have it, too.
• Accessible from Internet...
• Accessible from your mobile phone...
  
• Relatively nice and user friendly user interface...
• They even work on improving it while you sleep...

Actually, this may not be such a bad idea at all.
