Yours wouldn't be the first company crippled by legal paranoia.

I've never seen any such assurance in the licenses for any software I've
paid for.  Have you?  Python is licensed too, although you don't need to pay
for it.  Is there something magical about exchanging money in this context?
If so, send Guido a dollar?  I'm dying to see the look on his face when he
learns that accepting the buck opened him to unlimited liability <wink>.

Well, nobody is going to guarantee lightning won't strike you either.

The only hint of a legal issue I've encountered in Python's decade of life
is that CNRI believes the Python 1.6 license is compatible with the Free
Software Foundation's GPL but the FSF believes it is not.  If anybody has
ever been sued, or threatened with a suit, for using, distributing, copying,
or modifying Python, I haven't heard of it.  Guido has barked at at least
one person for distributing code derived from the Python codebase but
removing the Python copyright notice (in violation of the Python license).
They weren't sued either.

That's a bizarre mailing address, given the substance of your post <wink>.
