Sync Google Calendar and Appointment Plus

[Phateless]

I use the Google Calendar on my phone for personal stuff, but my company uses Appointment Plus (Online Scheduling Software- Appointment Scheduler Online) for professional calendering. Since I'm reselling this product, I use it too.

I have this little "schedule now" button in my sig, so you can play around with the calendar to get ideas.

If there is a good way to sync it to my Google Calendar, I would be super stoked.

Any ideas??
