Looking at the stack manipulation examples I had a terrible flashback of the time when I had to program in Postscript to print (generate?) labels with barcodes :S It is a quite interesting approach, and probably simpler than porting an existing compiler to a custom OS. The downside is that there's no software written in the new language, compared with the existing software written in Forth (perhaps? how portable is that software?).
