This is great news!  Does this multiple serialization support you have
in mind also encompass the serialization of mobile code?  Not being a
current Pyro user, I can't tell for sure what level of mobile code
Pyro currently supports; I can see that support for it has been a pain
point in the past.  I was about to subscribe to pyro-core so I could
ask about offloading Pyro support for mobile code to Picloud's
pickler.  Google isn't showing me if you've discussed that pickler
before, but if you haven't, I can tell you from usage experience that
Picloud maintains a good general purpose pure-python code pickler, and
its use could get Pyro out of the business of having to maintain one.

Here's a synopsis of how the picloud pickler works:

$ pip install cloud

import cloud, pickle
def foo(x):
    return x*3
def bar(z):
    return foo(z)+1
x = cloud.serialization.cloudpickle.dumps(bar)
del foo
del bar
f = pickle.loads(x)
print f(3)  # displays "10"
