But this is during the test suite, right?  In that case, it's going to
be a little tricky, I suspect, because the testing plugin already has
to make an ip0 instance so magics and other similar beasts run.

Could you make your class take optionally the ip0 instance as a
parameter at construction time?  This isn't very elegant, but it may
do for now so you can run in the testing environment until we can fix
it to decouple all the global effects.

In that case, you'd run your constructor passing it the ip0 instance
retrieved from ipapi.get(), and work with that.

Note that with all  the i/o capturing that doctest/nose do, this could
get ugly in a hurry, if you're also trying to do your own i/o
trapping.  So no guarantees that this will actually work.
