I hadn't thought of that - mostly because the devices underlying the iSCSI 
are already gparted (i.e. the iSCSI target is a GPT partition on an 
underlying disk).

I'm just trying it now - looks like it will work (Ok, it's created - I need 
to test failure etc.)

Is there any performance hit from having 'GPT within a GPT' kind of thing 
going on? - I suppose I could just share out the raw disk (i.e. /dev/daX) 
via iSCSI and then there'd be only one layer of partitioning going on... 
I'm not sure if that's a good idea or not :)
