   I very intentionally stayed away from such orgs. A little
   less money, but the happiness factor more than compensated.
   Got to pursue many esoteric projects - some of which WERE
   useful - and the org paid for most of it (except the odd
   Radio Shack parts).

   Really you DON'T want to send megabytes as IPC ... but
   somebody somewhere MAY wanna. So, what's the best way
   for them to do that ? Don't necessarily piss on 'em but
   help 'em out instead.

   Again though, just "blocks of information". MANY ways
   to do that. Each developer has to figure out what's
   best for THEIR particular app.

   I mentioned a server style app I made, but I wanted the
   child processes/threads (tried both ways) to return
   some active stat data to the parent. Not a huge amount
   of info, but useful. Pipes were the best way. The
   parent was allowed to xmit a 'kill' to a child in
   trouble, via the pipe, so it could shut down in an
   orderly fashion.

   Pre-threaded servers seem to have the highest capacity
   and throughput. The parent allocates maybe ten threads
   to start off with and then can add new blocks of ten
   as-needed. It's a little harder to manage than some
   other kinds of servers, and sometimes a bit harder
   to visualize how it's working, but they're good things.
   Once you've got it you're SET.
