Correct.

No. Or at least: Not yet.

I'll need to take a closer look on how/where the cHashs are actually 
calculated. But in any case, there is no out-of-the-box solution for 
this problem since there is no Typo3 API for this (tsfe can only delete 
cache by pid).

Is it required to have the events shown just in time of creation? 
Otherwise, you could look for a solution of a periodic cache clean...

Mmmh; this sounds a bit too long for me. Is this browser-dependent? I 
know that e.g. several versions of IE have really large rendering times; 
or maybe you have a complete set of all views in one page? If so, try to 
split it up into separate pages and unset all not required TS settings.
