I'm hoping to be able to manage with an off-the-shelf SuSE.  So far, that
seems to be working out quite well.  We had to disable a couple of daemons
(things like the cron daemon) - and with those out of the way, I get hardly
any disruption to my realtime performance.  Using the 'preemptable kernel'
helps too - but even without it, we are doing quite well.

However, I'm aware of the realtime varients and if I have to, I'll use them.

One of the BIG advantages of using standard Linux is that there is a massive
user community where I can ask questions (like this one) and get intelligent
answers.  The more off-the-beaten-track you go, the fewer people are able
to help in times of trouble.

So, as long as regular Linux can do the job, I'll stick with it.
