If you don't mind the resource burn (memory) of loading a lot of code over time without flushing it out when not needed, you could have the plugin files contain the methods without the enclosing class declaration. When you (re)load a plugin, you create a dynamic class name using a counter or some other uniqueness mechanism, build a string containing a class declaration wrapped around the file's contents, and use eval() to load it. You could of course let the coder put a class name into the plugin file if that looks nicer and do a string replace on it with your dynamic name. The key is that you cannot unload classes in PHP AFAIK so you must come up with a new class name each time. The old compiled bytecode will remain, but you can destroy the old plugin instance to regain a little memory. David
