I think last message from Sven even suggests the syntax were you get
boost::function. And you don't need a wrapper, BTW, you can just bind
function to a functional object which can do what you ask below

Isn't it better to always keep the plugin in memory?

Ah... this would need some wrapper over boost::function indeed.
