I remember Scala - ran it on Amiga4000 early 1993. A company has just reinvented some aspects of Scala for Flash. It's called RoboDemo: I feel that if Flash has been overhyped, it is also vastly under-appreciated. FlashMX which emerged this summer has some great stuff. An entirely new event model for one. Anything/Everything can be a button with dynamci behaviors aand more.. If you know Javascript then you can program FlashMX. Among the excellent new features relevant to kiosk apps are 'shared object' and 'local connection object'. Shared object is a cache support system for flash to enable persistence across sessions. Local Connection Object allows message passing between any flash movies being server from the same server. You can call functions between separate flash movies on separate machines in close to real-time. Both of these onlly require a few lines fo code to implement. A community of opensource flash scripts and components including 'prototypes' [reusable class extensions and customizations]has blossomed in the past year: In addition the Flash6 player can access video.still cameras and audio[microphone inputs]. Video/audio chat requires some serious bandwidth and more complex server installtion. But you can still use these stand-alone to remarkable effect. For example I did a very quick demo using two cameras connected to my Win98se laptop: 1. Logitech webcam on the USB port 2. Sony DV camcorder on firewire port. Flash detected both imediately. I am able to mask and drag live local video images around on screen and do motion detection in half a dozen lines of code!!! Combine that with local connection object and you have some killer kiosk features :-) AMybe not what you need now, but don't underestimate the scope and simplicity of flah now for interfaces. Plus you can generate a fully standalone executable in seconds, no licensing headaches. XMLsocket allows a dierct connection to remain open to any XML server anywhere. Bypass the http dance. Use it for sending non-XML data even :-) I think MM have a linux flash6 player out now, but not tested it yet. If so would likely run in Mozilla too! Best of all worlds maybe... Anyway, here the actionscript for two buttons to initialize, activate, and display two video cameras with rollover and motion detection. No need to fuck with ports [USB, Firewire], it takes care of all that. Just ask for Camera 0, Camera1 etc.. //VIDEO cam0_btn.onPress = function(){ cam0 = Camera.get(0); video_txt.text =; v.video1_obj.attachVideo(cam0); }; cam1_btn.onPress = function(){ cam1 = Camera.get(1); video_txt.text =; video0_obj.attachVideo(cam1); }; cam0_btn.onRollover = function(){ cam0 = Camera.get(0); video_txt.text =; cam0.onActivity = function(mode) { status_txt.text = mode; }; }; cam1_btn.onRollover = function(){ cam1 = Camera.get(1); video_txt.text =; cam1.setMotionLevel(10, 500); cam1.onActivity = function(mode) { status_txt.text = mode; }; }; ./Jason
