I am looking for an solution, for a website that I want to design. 

I would like to have a website that search in multiple shared agenda's for a startdate with time and a end date with a time. And would like to receive a True or False condition to show which people are available at that moment. This is a search on my own website and showing the people who have a True condition when they are available and not are busy at that moment.

I have searched and the labs those things are all very interessing but this feature I am missing this posibility. I know this is maybe to much to ask, but I would like to know or this posibilty is over there, now or in the future. Or is there a posibility to develop this kind of thing?

Happy New Year and hopefully you guys (or girls) can help me out. Thanks in advance.

With best regards,

Daan
