looking for an embedable calendar/scheduling plugin

The project I’m working on needs an embedded calendar/ scheduling module. I was hoping that something of that nature already existing an the rails community. If any one know of, or has a calendar that can be used to schedule appointments for service technicians, and is willing to share, I’d sure like to here from you.

Also, would anyone be willing to collaborate on a scheduling project, please contact me off list, and I’ll provide more details.
