After dinking around with an expensive three or four days trying to understand IPC::Open3 and trying to make things work I finally got it to work. I thought I would add my 2 cents and hopefully save someone else (or myself somewhere down the road) the same headache.
Yes, I know about IPC::Run. Unfortunately, the host I was required to use did not have it installed and I was not allowed to install any but my own stuff (I could have claimed it as mine for the purpose of getting things done, but I still didn't understand what exactly I was doing and didn't want to be required to fix something I didn't understand when it broke).

They aren't needed, at least for something this simple. Once I realized this I was able to get things working:
Any comments or improvements would be appreciated. I realize I need to add some checks for references and the like.
