It woudln't be. My point was this, you have a VFP class, right? When you want to use that class in a VFP environment, you can just call it as a VFP class. If you want to use it outside of VFP, then compile it as a COM object. If you want to gain remote access to that COM object through HTTP, use the Web Service (which is essentially just calling the COM, and COM is essentially just calling the VFP class).

So, if you have a situtation where you do not need the over head of the Web Service layer, you should just be calling the COM directly. Fortunately, the code that calls the COM is so similiar (as in identicical except for the creation of the object) that it will easily scale to use the Web Service if the requirement ever arises.
