I think it's very likely that this will happen soon.

For ASP and PHP there is attack-payload publicly available.
PHP and ASP have patches to limit the number of query-variables.

We're very lucky that there's no public payload for python yet,
and all non-public software and payload I'm aware of is based
upon my software.

But this can change any moment. It's not really difficult to
write software to create 32bit-collisions.
