At first, as many other open source program, I can't promise it's reliable. But I can tell you that, the first version of Kbox come from one of my project, which Is developed for HSBC bank (HONG KONG), and now I use it in my current project too. I developed kbox just for my project, so it might not be suitable for others, but if there is anything I can do, let me know, any idea will be welcome.
Finally, sorry for my bad english, lol:)
