[boost] [announce] Multi signature boost::function

Hi everybody, in Vault it is possible to download msf.zip, a (very small) file that contains multi-signature extension to boost::function It is possible to instantiate a boost::multi_signature_function::function on a mpl sequence of signatures and this object will behave as expected, in particular it keeps all the functionality of boost::function but allows to be called with different arguments types and/or number. Interested people could read (and compile) included test.cpp file, an example is better then 1000 words. If there is interest I can improve documentation and examples. Regards Marco P.S: This puppy should be compiler friendly, anyhow tested on g++ and MSVC
