[Catalyst] question about Catalyst and sharing data between different sessions

[denis at uzvik.kiev.ua]

Hi,
Does anybody knows how Catalyst shares data between different users/sessions?
I have idea to cache all used stateless objects (all
pages/validators/lists) at startup and then just use it by unique ID references from different pages. I.e just create 'object pool' (maybe we could use Memcached for this?) and use it from catalyst pages.

Any comment would be appreciated.
