Well, in fact each big application uses shared libs.

Okay, answer me at first on the next question.

1) forget for now about combo - app.

Let you want develop some App. It must have as Standalone so Client
versions. How you see this ?

IF we have 2 different V4RB plugins, then you need compile one app, using
first., and second app using second.

So you now must distribute 2 (!!!) compiled applications.
Agree?


2) As for me, I like idea in PrimeBase, when you make and distribute only
ONE application. 

Yes, in fact they do NOT have embedded engine like Valentina. They can only
talk to local Server via more optimized DLL. I think it simply talk not via
sockets but via some direct calls to Server.
Yes, so they have THE SAME sources. They do connect in both cases: local and
remote. 

Valentina work for local db as true embedded engine...but I like this
idea...Or you think that it is normal if you will distribute 2 versions of
your apps ?


3) you self have point problem with above way.
    How you will be able subclass Vdatabase? VCursor..
