Vim persistent undo with sudoedit

Hi,

I use persistent undo feature of vim. However, I use sudoedit
when editing files as root. This breaks the persistent undo since
it relies on filenames. Is there a way around this ? I tried a
few vim plugins (like sudo.vim) which didn't seem to work for me.
I am using either of them because a few plugins (like
neocomplcache) complain that they won't run as sudo (which is
right) since they run a few things in background. So is there a
way around this ?
