Push updates to FMS from ColdFusion (eg CFCs) - callbacks, RPC, notifications, etc possible?

How can I push updates to FMS?

For example:

A site visitor's status has changed xyz in our business logic.

We want to, eg, block the stream for him through FMS.

How can our ColdFusion code notify FMS of this change?

***

Is it possible to establish a lasting connection between FMS and ColdFusion (eg, CFCs) whereby:

CF would be able to call certain functions in eg our main.asc file in our FMS application?

***

A solution I've thought would use a proxy/relay: Ie, both FMS and CF can connect to a proxy socket server to relay messages.

However, my boss want to avoid adding another custom component if FMS/CFCs/etc support this type of thing.

Thanks!
