It is my understanding that python and perl both got their start on *nix systems, therefore, it would seem to me that a port based off these programming languages would be easier than, say, VB or some other "Windows" type technology. The problem with portability, as I see it from someone who had programming experience way back when, is the initial methods used to code the software in the first place. Now that we have GUI-driven development environments, it seems that it has become "next to impossible" to port anything from one system to another. I wonder if that is due to the fact that these GUI tools obscure the code underneath and some of the new software developers have less of an understanding of the underlying language? Likewise, from the user perspective, the GUI has "crippled" most peoples' intimate knowledge of the software and its interactions, meaning that you have to provide the same "GUI-style" interface to the *nix port or else the majority of the people will not know how to use the software. I am sure that there is a market for such applications on *nix systems, and they will surface. Maybe not from CL, but other sources who see the value in extending their portfolios to "non-traditional" OSes.
