This is getting kinda ranty. Fortunately, I have to drive someone to O'Hare. So, I'm going to calm down while I do that and then I'll be back to say more about how xv fits into this whole story. Stay tuned. 13/n?

So, xv had a special "polling" mode that you could use to make it continuously watch a file. If you were viewing the file and the file changed, then xv would update the displayed image. This was the secret sauce for making real-time dashboards. You'd have your physics code dump some kind of output file every so often. Then, you'd stick pgplot or some other tool on a crontab to make an image. Have xv poll the output file. It worked great and involved almost no coding. 14/n?
