Building multiple EXE's with common code

Question

I’m trying to determine the best way to use Application Builder to deploy a fairly large LabVIEW project to computers which do not have a LabVIEW development system installed.  This project consists of:
Multiple top-level VI’s, each of which should be compiled to a separate executables.
Multiple plug-in classes which are dynamically loaded by the top-level VI’s.
Common modules (LabVIEW classes, project libraries, and individual VI’s) shared by both the top-level VI’s and the plug-in classes.
Everything works well under the development system, and also when I use a single build specification to both build the EXE for one top-level VI and to place the plug-in classes in the correct folder relative to the EXE.  However, this seems wasteful, as it makes a full copy of all of the plug-in classes, and their dependencies for each top level EXE.
If I try to build the EXE with one build specification, and a source distribution for the plug-in classes with another build specification, error 1448 occurs when I load some of the plug-in classes using “Get LV Class Default Value.vi”.  I suspect that this is due to having the same common VI expected at two different paths (i.e. one embedded in the EXE and a second copy in the folder where the plug-in class is located).
Is there any way to use multiple build specifications to build several EXE’s and a “library” of common code in such a way that everything links properly?

It is possible, but I will save you the trouble - if it works as a monolithic executable, leave it at that. It may be wasteful, but computers are powerful, memory is cheap and headaches resulting from trying to manage dependencies aren't.
If you want, you can find some plugin schemes in the large apps group over at the communities area of this site, but you're probably better off not going into it if you don't actually need the functionality.
