Why not use it like this:

[module mymodule.py]
class MyClass:
    # blah blah
myinstance = MyClass()

Now we have the module with your much-used instance. This can be used 
by other modules as follows:

[module a.py]
import mymodule

mymodule.myinstance.do_something(x,y)

But maybe you tried this approach already?
