Several thoughts, Viesturs. First, since you are aware of VNC, in what way is it lacking? From your sketchy list of requirements it seems an appropriate choice. (full disclosure: I have found VNC to be a very useful tool; by design, it's a great cross-platform tool; I even have a VNC client on my iPhone!) Second, since providing remote monitoring and control necessarily means making the EMC2-controlled machine accessible from the Internet, are you keeping security first and foremost in your planning? I think you would do well to reach out, not just to us, but to folks who are skilled in making distributed hosts secure. (Simple example: I tunnel VNC through SSH.) Third, since your application involves your customers, keep in mind that many remote-desktop solutions have separate fee structures for personal and commercial users. http://en.wikipedia.org/wiki/Comparison_of_remote_desktop_software isn't great but it's a place to start. Regards, Kent PS - Jon mentioned the awful performance of OpenGL over the Internet. I had been hoping that WebGL would be the answer, but so far it's about as secure as a padlock made out of paper mache. PPS - I was glad to see you got your pipe-welding application working so well. I haven't touched my mathematical analysis of pipe intersections since my wife went into the hospital last month. She's home again but her recovery has been all consuming. The cure may have turned out to be worse than the disease. ------------------------------------------------------------------------------ 10 Tips for Better Web Security Learn 10 ways to better secure your business today.
