I commented on python-dev but maybe it is better to keep discussion here.  Could we make the frozenmodules thing into a dynamically loaded module?  Then you could have support for end users making their own.  E.g. a command-line param that lists a set of DLLs from which to load frozen modules from.  Then, if the command-line is not provided, we load from .pyc as per default.  If it is provided, we dlopen (or whatever) the DLLs and give the nice performance benefits.

Like Guido, I want to see the toolchain to build the frozenmodules thing.
