I have well over 50 such machines (growing every day). Distributing
updates to my Exim systems via propagating a shared module to all of
these servers would be _much_ easier than modifying Exim and
restarting. Also, the code generation and maintenance issue is
simplified tremendously -- I don't have to recompile Exim every time I
make a code change and I don't have to recompile my modules for new
releases of Exim assuming the API is preserved.

Beautiful.

As a thought: the "loadable module" system could have both static and
dynamic options. Apache (and others) have the ability to compile said
modules in during compile time. This might be a nice feature for
individuals who have dlopenphobia.
