|Cool. I'm also thinking of a hybrid idea. I've done this before.
The hint that the new data is available happens through "Push".
But the decision to fetch or not & the actual data-pull happens separately.
The notification mechanism will not be required if it's a consistently high-speed requirement like Sharemarket.
If the solution involves stopping data production intermittently, then a Push-notification mechanism to trigger start/stop could be useful.
Will try it out.
Thanks a lot.
