The Problem with Activesync stuff is always the potential license
question, what if MS will start claim license violations by Z-Push
(Justified or not does not matter) ?
I fully agree here about the licensing violation.
There already exists a sogo backend for Z-Push, a few posts ago is a
link for download.
I will try to make it better available, so we can work on improving it.
We could also import it on our source repository. We did this a while
ago from the connector developed by Philipp Kewisch, but he soon after
abandoned its development.
The one big advantage I see of ActiveSync is, that you have only one
setup to do for Email,Calendar,Contacts and Tasks and all traffic
flows via HTTP(S)
There are several disadvantages of ActiveSync compared to native
Cardav/Caldav support:
- Only ONE Calendar, Contacts and Tasks can be synched
- Only one ActiveSync account is possible
- Mail handling is very limited
Indeed but it should be compared with SyncML/Funambol, not
CalDAV/CardDAV.
I would still very much like to open a discussion about this - ie.,
Funambol (SyncML) backend vs. Z-Push (ActiveSync) backend.
To offer a very good mobile experience, I feel we'll have to make a
choice and focus our efforts into one or the other. We chose Funambol
many years ago. It might have been a good choice back then but it
doesn't mean it's still the best.
On my end (and speaking for myself only), there are some things I
dislike about Funambol such as a worthless bug tracker, patches taking
decades to get accepted (or even bugs getting acknowledged),
Java-based (enough said here), requires more resources than all other
SOGo components and requirements combined together and multiplied by
your favorite factor of the day (must be greater than 2), almost
impossible to package together with SOGo and more.
What I mostly fear about Z-Push is that we'll revisit all the device
synchronization bugs we had over the past few years with
Funambol/SyncML and we'll have to hack around like we did. This is
very valuable time and know-how here. Getting the Z-Push connector up
and running can be done in a snap, but refining it will take some
time. Also, having the Sword of Damocles on top of my head regarding
the licensing agreement doesn't make me a happy, happy, joy man.
The biggest selling point for the z-push style email for us was that we
could run it on port 80/443 and was approved to pass through the state
firewall. That and all apple and android phones already have clients for
it without having to download something else.
