This is somewhat achieved already. queries and handling of the conf is all done
in the library. cman/aisexec takes care of synchronizing.
You can already upload new configs and they are propagate through the cluster.
See the cman/lib/test.c code snippets that i did check in by mistake :)
it has one update_config example in 3/4 calls.

While i would generally agree on this bit, we are somewhat pending some changes
in the aisexec db that is still lacking some functionalities. I would prefer to
see a reliable and functional backend before switching.

Anyway 90% of the apps are ported.. modulo rgmanager and bugs..
