What are your real world uses for Aspect Oriented Programming?

Question

I'm stumped as to why adoption of AO has been so slow. There are plenty of rich implementations out there for the predominant languages. My guess is that, like OO in it's day, it is enough of a paradigm shift that people don't recognize the places where it could be helping them.

So, beyond non-invasive logging, what are some of the ways that you have used, or plan to use AO, that reduces complexity, improves maintenance, enhances system "ilities"?

I am currently using AOP via EntLib / Unity in production for:

• logging
• caching
• security
• exception reporting
• performance counters

Take a look at http://www.agileatwork.com/unit-of-work-with-unity-and-aspnet-mvc/ for an implementation of the unit of work pattern with AOP

[UnitOfWork]
public void Process(Job job)
{
    ...
}
