What would be nice is if someone took on the task of coding a "logic module" type DCE device. Something that could store (in SQL), set and read an arbitrary number of user defined states, could intercept any events, and issue any DCE commands. And critically, from the web admin, or just a .conf file, you could build sequence logic blocks and add them as config entries to the device for it to process. Then it could act as a programable sequencer module.
Each block of "code" (could be a basic script-like definition the the event/command to trigger it, states to check, and resulting actions based on this testing) would be loaded up by the device on reload and subscribe to the necessary events, etc (not sure if you can do synchronous even interception, which would kind of be important for several different purposes) and then behave as a much more sophisticated programable sequencer for any part of LMCE.... we would finally be able to access the true power of the DCE messaging system
