I'd be interested in helping doing this - of course we'd just have to
munge one patch or the other, but it's still probably straightforward.
Problem is I wouldn't have time to get to it for some time. How about
this, because collaboration rocks like this, give me some times when
you will be available over some direct medium (jabber, irc, whatever)
and we can get down to business and crack this out pretty quickly, I'm
sure.
