I would prefer to do this for security reasons. But I think I see the
question. If the memory is shared do all users have access to it. Or
can you do this by group. That way not all users will have the ability
to access the memory. If the daemons need to retrieve information from
the memory can the user ID they are running under access this
information straight from memory? Or will the library need to
authenticate itself to the daemon before it can retrieve any information.
This would mean that the only user allowed to access the shared memory
would be the daemon.

I think I am with blindcry on this one. I need more information on IPC
and SHM. How can we secure the shared memory segments from normal user
access?

Well this project will just be using a custom database. This means
that MySQL will still be free for use by the WFEs.

There is always going to be a breaking point. I am not sure about how
efficient MySQL can handle incoming requests. Obviously if you were to
have the time to write your own database it would be much quicker.
Simply not needing all the extra crap that MySQL has in there will speed
things up immensely. For now I say we go with it and hopefully darkside
and MySQL can handle the requests with a fair amount of speed.

So here is the other question. I was expecting that you would be
writing the WFEs for the account management stuff. Do you think that you
will have the time to work on the other portions of this project? I know
that next you will be tackling the Distro server. While you are doing
that we are probably going to work on the database and the billing
system. With the billing system out of the way I can gain some spare
cycles and work on the more important stuff. I imagine that these two
steps will take about as long as it will take you to do the distro
stuff. After you are finished with the distro stuff will you be joining
us on this project? Or are there other things that your going to try
and do after the distro server ( like fix bugs in the news server =P )?
let me know what your plans are after the distro server.
