Yeah, it seems so. I thought I'd resolved free/busy issues before I
released 0.9.9, but it seems some are still extant and I'm working on
it.

They should be additive, for any given resource. Grants from a
collection apply in place of grants by a principal, however. I'd be
interested to see more detail off-list on the problem you describe.

I've tried to write these up in some further detail on the wiki, but
it's taken a while for me to come to grips with the exact meaning as
well.

These are the rights defined in the RFC (well, Draft RFC, for CalDAV
scheduling :-)

As I understand it, the rights granted by schedule-deliver are related
to querying free/busy and inviting a person to a meeting. The rights
granted by schedule-send are related to supplying free/busy and
accepting(/declining) an invitation to a meeting. So while it is normal
for a user to grant the schedule-deliver set of privileges to everyone,
they would only grant the schedule-send set of privileges to someone
like an executive assistant.

Each of these privileges splits into three, for really fine-grained
control, but to be honest I'm not sure how useful that is in the real
world.

Yes. It seems that the caldav scheduling support in 0.9.9 which will
make iCal users happy, tickles a bug in the nascent scheduling support
in lightning.

Once I figure out a workaround for this problem I will release 0.9.9.1
with the fix.

Cheers,
Andrew.
