Hi to those folks that contributed to some recent messages related to threads, active objects and reactive objects. Mostly this was Matthew Vogt. So this is mostly for Matthew but anyone else can certainly respond. I have been interested in proposing an alternative threading model to that provided by boost.threads. Quite sensibly somone suggested that any alternative should leverage the existing facillity. J. Garland also provided the reference to the work of Schmidt; the ActiveObject pattern. I have been trying to slice off a piece of a larger library that I have been working on. Defining something that would be appropriate as a proposal to boost is very difficult. I started a requirements document to that end which become more of a research paper. Its convinced me that it is probably a no-go. The fundamental reason would be the scope of anything with pretentions to calling itself "active objects". It requires not only a significant body of supporting code but requires quite a cultural change by users (i.e. developers). I would have posted the document but it is quite long. If anyone is interested in it then just ask for it. Its a rambling piece but it has been reviewed :-) Cheers, Scott
