Checking conflict on an implicit resource.

Hi,

First of all thanks for making the release :) I have a question related to checking for conflicts when a resource is implicit. Lets say I am allowing for online classes and I have teachers as my resources, lets say I have 5 teachers but only 2 online classrooms (implicit resource, not directly selectable by a prospective student) I have set availability on my teachers in a way that they are available at different times which overlaps but my online classrooms are 24 hrs available. I want to allow for booking a teacher only when a slot in either of the classroom is available for the teacher to conduct the class which will make the classroom as a resource as well but I don't wish to show that as a bookable entity, it should be there as a implicit resource but conflict resolution would take into account the availability of the classroom as well, if there is a classroom free for that slot or not.

I can write code, so if you can give pointers or maybe its just doable by doing some availability settings.

Thanks!!
