	Hi,
one more function would be needed, to tell backend from the client that
it may stop delivering free/busy information and/or focus on a new
query. Otherwise you may get responses really any time, which is not
what you actually want.

It all seems to me like an ECalView for free/busy, rather than anything
doable on the backend client itself.

Remember the factory shares backends between data-book/cal-s. With
views, all known are notified about changes on objects (if they belong
to the view), thus even as a view this will not be that easy on the
server side to do, with some hard management of who (EDataCal) is
looking for what (different users, time interval...).
