You may have look at the IRC client in applications/camlirc of the lablgtk source distribution.
It tries to do things in a reasonably modular way.
To allow repacking components, one just adds a ?packing argument, which is forwarded
to the most external container inside your component.
To allow communication between components, you can use the ML signal framework
provided by GUtil.ml_signal.
