I'm currently working on a ServerSignal utility class which has a similar but somewhat limited interface as boost::signals. The main purpose is so that I wouldn't have to create containers to hold session data every time I want an inter session communication. Currently it does work but has missing features and I'm still working on it.

It is to features the following

• Uses WServer::post()
• Uses read/write thread locking in the ServerSignal utiltiy
• Creates trackable connection with WObject
• Allows 2 kinds of emit functions, one with arguments as specified by template arguments, one without argumens(a hacky version currently implemented)
• Allows up-to 6 arguments as Wt::Signal(Only using 2 specialized classes during testing, will add the rest when every thing is complete)
• Gives information about sender(WServer*, WApplication* should be implemented with WServer::post())
• Uses WApplication::bind() (should it be used internally or externally?)

TODO

• Make connection trackable with WObject
• Use a different method to accept 0 argument boost::bind(Can't be overloaded, can't be template generalized because boost's bind_t doesn't implicitly convert to boost::function when signature is generalized)
• Create a way to get sender WApplication pointer when ServerSignal is emitted

I posted this because I'm new to function objects and template programming. If Wt team is interested, it may reimplement this in any way.
