How can I see My Photo Stream from two Macs associated with the same Apple ID?

Question

I have a MacBook Pro (my personal machine) and an iMac (our family computer).
The iPhoto library housing all of our family photos lives on the iMac.
The iPhoto library on my MacBook Pro is currently empty.
I have an account on both machines.  I have associated the same Apple ID with both machines.
When I launch iPhoto on my MacBook Pro and attempt to turn on photo sharing (so that I can see My Photo Stream, as well as other shared streams), iPhoto informs me that "iCloud Photos for xxx@xxx is being used with another library named 'iPhoto Library'."
My iPhone, which is also affiliated with the same Apple ID, shows the streams just fine.
What can I do to remedy this situation?  I'd like to be able to view my shared streams on my MacBook Pro, while leaving the actual massive photo library on the iMac.

I found out about this issue when I created a new library with some photo's I wanted to sync to my iCloud account.  I found the following on the Fat Cat Software page and thought it might be helpful to others:
Using Photo Stream with multiple libraries
Starting in iPhoto 9.2, Apple introduced a new feature called Photo Stream, which lets you automatically transfer photos via their iCloud service between your iPhoto library and your other devices such as an iPhone, iPad, or another Mac. This feature works when you have multiple iPhoto libraries set up, but there are a couple things to be aware of.
First, iPhoto will only allow Photo Stream to be active in one iPhoto library at any given time. If you've already enabled Photo Stream in one library, but then open a second library and enable Photo Stream there, this will cause Photo Stream to be turned off in the first library.
Any photos downloaded by Photo Stream are actually stored in an entirely separate location from any of your iPhoto libraries. This means that, even if you do switch Photo Stream from one library to another, you will not need to go through redownloading all the photos you already have in Photo Stream back from the iCloud servers. So, switching Photo Stream from one library to another is a relatively inexpensive operation, so you can do it as often as needed without it being much of a hassle.
