Yes, I started the last one on that topic. This culminated in my BrowserDetection unit, which you can find at: http://home.tiscali.nl/~knmg0017/software/fpc_laz/browserdetection.tgz (You have to take care to set the include paths in the IDE) It works for Win, Linux and probably (but I cannot test, so feedback is much apppreciated) Darwin.
