Yes, I definitely believe that it has some good cross-platform properties. Object orientation was one of the techniques I used to make Python platform independent.
The second stream of material that is going to come out of this project is a programming environment and a set of programming tools where we really want to focus again on the needs of the newbie. This environment is going to have to be extremely user-friendly.
There was a project at Lawrence Livermore National Labs where many years ago they went down this path for scripting and controlling very large numerical calculations.
Invariably, you'll find that if the language is any good, your users are going to take it to places where you never thought it would be taken.
I think the real key to Python's platform independence is that it was conceived right from the start as only very loosely tied to Unix.
