OK, I finally finished a version of a document I have been promising to write. We put it on our site: OOMessagingCommandPatternStatePattern.
In it we present examples of the following in LabVIEW:
messaging with LabVIEW objects
Command Pattern (with XML configuration files application example)
State Pattern
Hopefully the examples will be helpful to some readers, and promote further discussion on scalable application architectures.
