Okay, we need to put mobile device configuration on the server, 
because activesync does not allow to offer the clients a way to transfer a few 
settings. (If it would we could save the configuration on the device which is 
something I would conceptually prefer.)

Any mechanism we invent to do so, should be as generic as possible 
to maximise its use.

Because this is a limitation of activesync, the suggestion is to 
use "activesync" as name for a IMAP folder annotation and to save within each 
folder if it should be synced for a number of different devices.
This indication does not seem to be useful in general as
another sync method, let us call it betasync, might not need such a 
limitation.
So up to now I am okay with using "activesync" as the name of the annotation.
I think it is okay to use an annotation, because this configuration needs to 
be per user on all folders, including the ones that are read-only. An IMAP 
server already has something similiar with the \seen flag, so it will be 
doable. Using something else like a special IMAP object will pose problems 
with doing this per user, e.g. because of the read-only support or it will be 
farer away from the folder.

Because the default will be to not sync a device, I think we can do this in a 
simpler way like:

   {$udid} *{<SPACE> {$udid}} 
 
where $udid is a unique device id not containing spaces,
which is similar to how entries are separated 
in  /vendor/kolab/pxfb-readable-for
see 
http://ftp.intevation.de/users/bernhard/scratch/extended-freebusy-concept-0.92%2Bdev20080503-ber1-pub2.pdf

In order to make device numbers unique we could propose prefixes in the kolab 
space like "iphone-" or backendspecifics like "zpush12-".
So it would be come "iphone-123456" if we are sure that 123456 is a unique 
iphone number. 

So an entry like "iphone-123 iphone-789"
would mean the devices 123 and 789 would be synced with this folder, all 
others would not.
