By the way, do you plan to parameterize the number of arguments allowed, using maybe preprocessor metaprogramming? Yes I know that this is quite ugly, but do not limit the user of the library.

Can you show me it could be done. I've started playing with boost::mpl but still do not see I could apply it for variable arguments.

No, you can't have variadic templates with template metaprogramming. Sorry, you should use PREPROCESSOR programming. I have never use it yet, but waiting from variadic templates it seams the single way. See http://www.boost.org/doc/libs/1_35_0/libs/preprocessor/doc/index.html.

Let me know if I can help you with the shared memory issues.

That'd be great. I'd integrate and reflect that in the header. If you go ahead with that, please wrap that in

#if 1.35 < BOOST_VERSION #endif

so that it still works with older versions of Boost that I have to use.

I was proposing to help you with the shared memory issues, not to do it. Any way, I could start with the first ideas, but I can not manage with the tests.

Thanks, Vladimir.
