:I always thought Nathan was working with gcc. And I'm *sure* Physmud++ is 
:threaded - isn't it?

:Any comments on the above? I would really like to start with threads, 
:rather than decide to rewrite nearly everything at a later date; but 
:would it be more hassle than it's worth?

:Those who have a threaded server, what OS/dev tools are you using? Is 
:Linux currently the wrong choice for anything serious in this area?

I'm using g++ for the solaris version, but I am using solaris threads, not
pthreads, and with my own wrapper library. And I'm not using libg++... not
even for io, which consists of my own wrapper library for sockets, loosely
based on (but not using) Socket++. File io is done through a modified
version of the same. And I don't have a database... the threads operate
over the containment layer, which means concurency is never an issue.
(message passing needn't be concurent, exactly)
