[I am not familiar with openbugs nor its licensing terms, but seeing as 
it is distributed as part-binary-only...]

I agree there is little technical reasons for dlopen() vs a simpler
stub, but there is occasionally licensing/legal reasons for doing so - 
GPL-licensed code dlopen()'ing proprietary-licensed binary-only DLL/so
is allowed, but a 'more intimate' linking of GPL-code with more 
restrictive code is sometimes troublesome in its licensing status.

(for private/internal use, there is no reason for going the dlopen() 
routine...) Just an idea...
