The _[] namespace may be of use here.  If there is a way to grab the _[]
namespace you should be able to access the REQUEST variable.

The other option is to hack _bobo_traverse (this is called to find the
method which is eventually called I think) so that it grabs the REQUEST
for the upcoming __str__ method.
