Unfortunately I don't have enough disk for this... nice idea though!

Phew! At least I am not the only one who feels like that!
This is for my home system, but at work, since discovering the 
non-workingness of pvmove, I have tried to make sure that we don't have 
to use it...

Absolutely. I am actually amazed that its still like this after so long.
I mean, whats the problem? Is Redhat blocking it somehow or what?
(I sort of sniff a scenario where Redhat have some proprietary volume 
management system in the pipeline and want to discourage people from 
using LVM2 so that they will be more likely to but into Redhat 
Enterprise Server or whatever, but maybe thats just paranoia speaking 
and I should just take the tinfoil hat off and let the rays in)
