	Hi,
I rethought my thoughts about this and I think I follow your idea more
closely now. If I try to rephrase it, then it might be:

On the server side, add new
   e_data_cal_notify_free_busy_data (..., const GSList *ecalcomps);
which invokes a signal on the D-Bus connection about (partial) result
for a free/busy request (note it doesn't provide user separately).
This signal will be valid only while a get_free_busy request is running.
Calling e_data_cal_notify_free_busy_data() out of these functions will
not fail, but the ECalClient consumer may not expect that being done.
With this limitation we'll have a possibility to cancel pending request,
if needed. The e_data_cal_respond_get_free_busy() will have no return
values.

On the client side, the 'finish' function will be also void and any
information about free-busy will be available exclusively in a
"free-busy-received" signal, which will have a parameter GSList
*ecalcomps.

I hope we are on the same line now. If you agree, then I'll make a
change in this way.
	Thanks and bye,
