We have a business unit that does marketing databases.
He works "there".
We have a print unit that does direct mail.
I work "here".

I've probably got far more experience installing and maintaining Oracle instances than him, but I'm a busy guy, he's not, so I figured I could let him do it.

So I asked for his time up the chain, over the wall, down the chain.

He has no ownership of it, and when it crashes, it will fall to me to make it right.
