An interesting idea, to be sure, and one I have looked at to some extent. One thing that I've never quite learned is whether the included curses and curses_panel modules statically link a copy of the ncurses library on *ix systems or whether they invoke the ncurses.so library dynamically. If it is designed to invoke the ncurses and panels subroutines from the shared library it could be a possible path. One obstacle I thought that I saw is that building cpython modules based on non-python library sources AssUMes that the build process can get the library source from the cpython repository, rather than from a non-python external source repository. I have built some scripts to get around that assumption, but they would have to be integrated into the cpython external library build process for any wide distribution. And there are some differences between the PDCurses and ncurses assumed internal structures and what is externalized and what is not that might make that harder than it first appears. Plus taking that path really does requires the porter to learn at least the generics of the cpython internal macros and functions in order to be able to debug the result, which is a little bit daunting. Not impossible, but many molehills look like mountains to the uninitiated. Anyway, I am just investigating options at present, so thanks for the suggestion.
