Some clarification about this:
In the end applicability will say if this convenient or not. 
One has to be aware this tends to favour sites more than rich apps.
For rich apps, like the ones we make with Seaside :), you may well decide to
maky user pay for the more likely to happen requests in favor of faster response
times a posteriori.
