Hi Dejan,

I confirm Lightstreamer is currently based on a "publish-on-demand" paradigm, but we will support "publish-always" too in the future.

In the meanwhile, if you use the technique suggested by Giuseppe, you can make it extremely efficient by specifying a very very low update frequency for each "fake" subscription. This will make no actual data actually flow on the connection, while still keeping all the items subscribed too. Let us know if you need us to expand on this.

Thanks,
Alessandro
