Of course, there is a security issue. By default, the web site does not have authorization to open a command prompt to any computer, but I have a special peer-to-peer policy I can use to override this and allow the site to get access. The problem of course is that if someone hacks the web site, he can have access to people&aposs computers…. not good. So, while all of this is very cool, it may only be useful for demos and exceptional cases.
