Well we are hoping to release a Linux and Mac version in 1 or 2 years. Unfortunetely much of Hal is currently programmed in Visual Basic which is a langauge that only exists in Windows. However, our programmers are working hard at converting Hal function by function into C++. In fact, in a few weeks we will be releasing a small free update to Hal. Among other things, this update will speed up Hal's thinking by 3 times because we have converted many of Hal's bottlenecks into C++ code. We will continue converting the rest of the program into C++ over the next couple years and when that is complete it will be possible for us to port Hal to Linux and Mac.
