Is it possible to run ShareJS in a multi clustered environment ?

Hi,

First of all, Big fan !
I am using ShareJS + Code Mirror to develop a collaborative code editor. So far things have worked out pretty good. However, I am having difficulties finding a way to make it cluster friendly. I know I have to tap into livedb and publish that data across redis and then from the subscriber's side, feed the data to livedb client.

1) Is that something doable ?
2) If it is possible, how would ShareJS behave when multiple livedb clients try to save data into single mongodb database ?

Any hint / help would be great.
