Just a wild idea: 

Does it make sense to have several incarnations of the shared object file
_tkinter.so (or _tkinter.pyd on WinXX)?

Something like _tkint83.so, _tkint82.so and so on, so that
Tkinter.py can do something like the following to find a
available Tcl/Tk version:

for tkversion in range(83,79,-1):
    try:
        _tkinter = __import__("_tkint"+str(tkversion))
        break
    except ImportError:
        pass
else:
    raise

Of course this does only make sense on platforms with shared object loading
and if preparing Python binary distributions without including a 
particular Tcl/Tk package into the Python package.  This idea might be 
interesting for Red Hat, SuSE Linux distribution users to allow partial 
system upgrades with a binary python-1.6.rpm
