Is it a good idea to have the duplicate field names in child models?

[viperfx]

class Organisation(PolymorphicModel):
    name = models.CharField(max_length=255)

class NationalNode(Organisation):
    email = models.CharField(max_length=255)

class PatientNode(Organisation):
    email = models.CharField(max_length=255)

Is there any issues that can happen with this type of setup?

Note: The email field may not be present in all child models.

Not the module author (and just getting started using it myself), but I don't see why that wouldn't work, just that you wouldn't be able to query for email across different sub-models. If it is in most instances, though, it might be better to include it in the base model but nullable. Kind of depends on how you intend to query it.
