Attached is a sketch of a publish-subscribe solution inspired by the design of the native queue functions. Open the project and launch the Simple Demo.vi to get an idea of the concept (or create a few instances of the example templates and run those). As you know there are *lots* of messaging solutions out there that also support many to many communication, many of which are much more advanced. They are often based on user events, and LVOOP. I have still been missing a solution that is as easy and intuitive to use as queues though. I also wanted to overcome a few other issues with user events: - I do not like to always have to have an event case for each subscriber. - I want each subscriber to be able to preview or flush its incoming data stream...(not fully implemented yet, but logically simple to do) - and I want to be able to keep a channel open for as long as anyone is interested in using it, not die when the process thathappened to create it goes idle(which is what happens with queues and user events...). I am publishing this to get some feedback on the concept (as it is now it has lots of missing logic and the design is not thought that much through). Do you find it useful or just silly? Are there other solutions out there that are just as simple? PS - The original attachment was LV2014, I have now added a 2012 version as well.

I am working on a cRIO based application in which I am using some SEQs and these SEQs are being used within different parallel processes... Is there any difference in terms of processing to keep SEQ's reference in a shift register or to obtain the SEQ reference (using a name and "Obtain Queue" function) each time it is used? Thanks for any comments.
