Maybe it isn't good practice, I don't know. But I am working on an Availability Calendar class right now that displays 3 Calendars at once.
The approach I took was to load the Calendar library into my custom library so mine could have three instances on it.
Maybe I missed a better way of doing it though.
So, I guess then, that you haven't found any downsides...
Hmmm... I'll have to try that.
