web2py runs flawlessly in Python 2.6. I've been running it for several
months. All python code (web2py included) that runs on 2.5 runs on 2.6
as well. The inverse is not true however. The main purpose of Python
2.6 (and the upcoming 2.7) is to facilitate code migration to Python
3.x. It serves as a bridge being as close to compatible with Python 3.x
without breaking 2.5 apps.
If you run Python 2.6 some standard library modules might issue a
warning about using deprecated features (cgitb comes to mind) but that
is about the only difference you'll see.
web2py currently has no plans to support 3.x due to its backward
compatible nature. Something will eventually come along but certain
standard libraries are badly broken in 3.x that need fixing before
porting a web framework is really plausible. These items needing fixing
are the cgi module and the email module it depends on. Work is
currently underway to fix the email module. Once that is done, I plan
on submitting a patch for the cgi module. Once these issues are
addressed, I predict that Python 3 will become the web-language of
choice due to the possibility of unladen-swallow being merged in.
I write my web2py apps in Python 2.6.

Ah, I'm browsing through the web manual and found this statement which
left me with more questions:
"web2py runs with CPython (the C implementation) and/or Jython (the
Java implementation), versions 2.4, 2.5 and 2.6 although "officially"
only support 2.5 else we cannot guarantee backward compatibility for
applications. "
So then python 2.6 is supported "unofficially"?
Would it imply that some of the features from 2.6 are not supported or
that the framework has not been tested as thoroughly on 2.6?
