Yes, using python standard library seems like the way to go.
Generally, I recommend Sugarlabs to document clearly in source of the various components (e.g. in an INSTALL file) which versions of Python the code is expected to work against, and which version has been extensively tested.
One thing is that Debian do not currently ship Python 2.6 as default version of Python. Another is that we ship multiple versions concurrently, and attempt[1] to allow users to choose at runtime.
Currently I package Sugar packages with the assumption that they all work with Python 2.5 and newer - but it would sure be better if you explicitly stated which version were a) believed working and b) actually tested.
...or that you provide refression tests, so that distributors can automatically discover if some odd setup suddently stop working at a "minor" Sugar update.
- Jonas[1] it is often difficult to package for multiple Python releases, so some package maintainers choose the easier approach of only packaging for whatever is the default version (which allows Ubuntu to switvh to their often newer default version with a simple rebuild of same packaging, but does not allow users at runtime to switch to a different version for that Python module - and all dependent modules).
