I need a piece of advice from you fellow VB programmers

I am working on an administration application that exchanges data on a client/server basis. What I wish to do, is to offer the user (through the client application) different graphical interfaces for different parts of the system. Sort off like HTML is a standard, but still can represent various interfaces for each purpose.

What I thought I could do, was to send a list of tools to the client application, and then when the user chooses one of the tools, an Active X Control/DLL is downloaded and displayed on the screen. That way the client applications is always up to date and can be expanded without having to replace the entire software each time something is changed or added to the system.

However, it seems quite unprofessional to download, register, and then CreateObject to display a tool within the system. Does anyone have any other ideas? I hope you understand what I mean, it's quite hard to explain...
