[Sorry in advance if the deletion of my previous reply didn't catch up with all the news feeds. My mention of "SPAWN" in that post was not a valid answer in this context.]
No, the IDL_IDLBridge objects can only *directly* access process data on the same node so by itself it's not a solution.
You would need something more like Remote Procedure Calls (described in the IDL External Development Guide), which are quite low level.
If you're looking for higher level semantics, your bridge executions encapsulate discrete "tasks" with inputs and outputs, (and you have a budget), the ENVI Services Engine is more aligned with this goal. This is a separate product and though the name includes "ENVI", there's no requirement to use it in your processing.
But if your needs are somewhere in between, keep an eye out for an end-of-June IDL Data Point blog on the exelisvis.com website where I'll discuss the coming-in-8.5 officially documented support for server side SOCKETs. You would still need to build your own protocol for exchanging physical data between the processes, but it's generally a manageable goal for problems of middling complexity.
