Agree, cause of that I hate flash & java (and for many other reasons). Just one more recommendation - if you need multimedia goto 1Gbit switch (not hub!!) and cables - its almost the same cost like 10/100mbit and backwards compatible. (for the same (if) very low money is better desktop2server system, like old 64bit HW with Xeon1 and 512MB not upgrade-able (because of price and ECC) from ebay) Of course, for commercial with 20+terminals only new IBM/Intel/Dell (OK, or other manufacturer) dual/quadrocore with SAS is preffered (as much RAM as possible, 2GB very minimum!) -- 've a nice day!
