First of all, sorry for being so late. I've just paid no attention to
users mailing list, sorry about that. I promise to stay tuned.

I don't know this. For the moment I've even started to implement 
named_fifo. It should be easy, though. I also don't know how hard is to 
program a service for Asio. The ability to plug new events in asio would 
very interesting, for example, as unique wait point for all process 
asynchronous events (thread, network, file...).

Current cvs has this solved,It was already in cvs. Thanks.

Already solved in cvs.
