Hi Brian,
Have you considered using something other than the INI-style file format?
ConfigParser works best when there is a fixed, known set of keys: it
doesn't work so well when you want to use an arbitrary collection where
you do not know the keys in advance.
Bluntly put: it does sound like the INI file format and what you
ultimately want is not meshing well together.
Let's clarify the requirement: you want to have a mapping from services to
their configurations. Ignoring the format of the configuration file for
the moment, it sounds like you ultimately want to parse the configruation
and get:
{ 'apache' : ('http', 80),
... }
where a 'machine' is the key into the corresponding (protocol, port)
value.
If you are just prototyping this, a 'module' file like:
####################################
### machine_config.py
machines = { 'apache': ('http', 80),
## fill me in with the config of other machines
}
####################################
could be used as your configuration file format. The value portion of a
dictionary can be an arbitrary value. Here, we map a machine's name to a
tuple containing the protocol and port. No string hackery is involved
here.

I think you're making this problem too hard for yourself.

Can you show us the situation you're talking about that requires this?

Try to do so. I think this is a real point that needs to be cleared up.

Take a look at:
http://www.python.org/doc/faq/general.html#why-isn-t-there-a-switch-or-case-statement-in-python
If you need more examples, ask, and someone here on the list will be happy
to help.
