Blah, blah, blah, security, blah, etc. If you are behind a modern router, you're fine.

Back on topic, DrPop, let me guess how it feels to see all your tasks in one manager...KING DICK! Holy crap! Why has no one told me about this before?! THIS is how it's done!! You can so easily se where there are issues that need attention without checking on each machine one at a time. Oh, and be sure to expand on the colors. I use (say) vivid green for running tasks, medium green for waiting tasks, and light green for unstarted tasks. A similar scheme but blue, for GPU tasks. And bright red for suspended, and eror tasks. Now you actually control your BOINC world.
