Let me reiterate the way to get class methods:

class Function:

	def __init__(self, func):
		self.func = func

	def __call__(self, *args, **kw):
		return apply(self.func, args, kw)

class SomeClass:

	def class_method(a, b, c):
		return a+b+c
	class_method = Function(class_method)

At the addition of a constant overhead (the "Function" definition), and
one-line per class method (which you'd need anyway, to signal it is a
class method), you get a no-brainer solution.
