@You can use C++, but keep in mind that you cannot export a method of a
class.
In IDL (at least in version 5.2) you can also make a dynamic loadable
module (DLM). Dependig on what system you're on, this is a DLL or shared
library.

@In IDL the functions you put in the DLL become a part of the IDL system
routines. This has some advantages in error handling and an easier
interface to the routines.

@Not if you have the source of the DLL.

@Basically make sure you have some wrapperfunctions to access the
objects you want to manipulate.

@More information can be found in the "External Development Guide"
