That is a valid concern.<br>
<br>
I think making our entire sync product based on polling is
a bad thing.<br>
(Battery, performance, etc etc etc).<br>
I think making sync based on TCP sockets/WebSockets/SockJS
is a good<br>
thing, but it is past 1.0<br>

<div>regarding 1.0 - I am not even sure what that version
should be done; but for me (personal thought),</div>
<div>I (again, personally) have serious doubts that the
first sync offerings (March/April?) will be the ones
labeled as '1.0.0';</div>

I think one of the minimum features for our first client release
should have is push initiated synchronization.<br>
<br>
This doesn't mean push based or real time, just a push message
causes an update.<br>
