Just a stylistic point. It's easy to second-guess someone else's code
when you have the liberty of scrutinizing it at what I sometimes
laughingly call "leisure", so I don't want this to be interpreted as
being critical, but the code might (?) be easier to read (barring typos) as:

class roForm(forms.Form):
def __init__(self, *args, **kwargs):
self.readonly = 'readonly' in kwargs
if self.readonly:
kwargs.pop('readonly')
super(roForm, self).__init__(*args, **kwargs)
if self.readonly:
for key in self.fields.iterkeys():
self.fields[key].widget.attrs['disabled'] = True
