Sure!

I think that's a much idea than "munging" the vmi schema.  Can
you
provide me (either on or off-list) a sample of which fields of the
Display schema are filled w/ what zone minder information?  As an
example, I could include the monitor's name as some text that goes into
"line1", etc.  Or, more powerfully, I could allow the text
inserted into
each Line to be a regular expression to include certain special
variables (e.g., <monitor_name>).

Just to clarify, the URL above is a "live view URL--not the URL for an
alarmed event.  That means that whatever caused the alarm may or may not
still be visible by the time that a user decides to look (and whatever
delays might be encountered by grabbing the images).  Since there are 2
URLs (a URL and a Link), maybe one could be used for live and the other
for the alarmed event?

Should anything be sent when the alarm ends (wrt Display)?

I had also thought that I had seen some reference to pre 1.22.0 being
somewhat buggy in this area.  However, this brings up a good point of
discussion--how to resolve control "master".  If I allow xAP
messages to
control camera positioning, then I would think that I should also force
zm to no longer control positioning--else you get a "fight" going
as
observed above.  I'm pretty sure that I can remote disable zm's control,
but that also implies that I will need to support a zm control
"resume"
command via xAP.  Unfortunately, there's nothing that I can do about
localized camera control (e.g., your cam's PIR).

I also plan to introduce additional support for temporary zm motion
event "suppressions" and "resume" so that the simple
act of moving a
camera doesn't introduce artificial alarms.  Initially, this would be
manual (i.e., the xAP "controller" would need to send out these
messages).  Later, I could add logic to automatically apply them on a
xAP-initiated "move".  This could also be useful to reduce false
alarms
if you know (from other HA-sensors) that a camera should be allowed to
create alarms for a brief period.

FWIW: I've now fully switched to the new 1.22.0 API and plan on some
sort of a next release by next weekend.  The implication is that all
future zmxap releases will require zm 1.22.x.
