Hi,

To follow myself up, we appear to have fixed the dual-homed problems and 
can copy files in and out of the SE from internal and external machines. 
Tests are starting to pass again (woohoo!).

We're leaving it a while to see if any more problems were being masked 
by anything we've fixed. If we're clean we'll probably push ahead with 
migrating our pools and getting some space before attempting to break it 
all again with the SRM2.2 spacemanager ;0).
