Accessing arbitrary template values in widget templates is not possible,
IMHO, but you can provide selected values from the template to your widgets.

Make a form widgets subclass that accepts an additional parameter, e.g.
"extra_template_vars" and then when you display the widget in the
template do:
${form.display(value, extra_template_vars=dict(site=site, foo=bar, ..))}
Then in the form widget class provide an "update_params" method like
this (untested):
class MyFormWidget(widgets.Form):
params = ['extra_template_vars']
extra_template_vars = {}
def update_params(self, params):
params.update(params.get('extra_template_vars', {})
super(MyFormWidget, self).update_params(params)
