I played with the demo - this seems to fit my need.
I do have some questions though -
1) Is it possible to have different calendars for different users?
IE - if different entertainers that have accounts on my promotional site want to list their show dates, then the calendar should show their entries and only their entries. Is that possible? It also would be cool to let a user select a location and date range and see all entertainers who will be there during that date range.
2) I get the impression you use ZendEncoder to protect your source. I don't have a problem with that, but then if I can't fix things myself I will need to know that this product works with suhosin (both core php patch and module) - as I won't run the product if it doesn't and being closed, I can't patch it myself if it doesn't.
I actually am only running suhosin on my live server, so I can't easily test the downloadable demo to try it. Not w/o rebuilding my php anyway.
The live server is running php 5.2.5 on CentOS 5.1 if that matters.
