We're planning on doing a comet channel to a server that potentially runs beside other servers in a high-availability environment. If I have a global queue of requests that I want posted to a given channel, what mechanism do people use to replicate this among the other servers in the HA group? I can imagine using a database is one idea - but my point of using a comet channel is to get quick responses to simple events happening without the need to repeatedly poll a database. That leaves message passing between servers as the only other viable solution.
An example is - I just posted a request to a server and somehow I get reassigned to another server. I want that other server to know that I want certain types of events - without the client having to re-request them.
