A couple of months ago I had a training in Codys BOP4 fundamentals and this week I developed my first demo bpm process with it.
And I must say i was really impressed by the speed of development and out-of-the box functionality of the product!.
The power of the product is the BPM part, but it also has an integration part.
You can download a VM image here and there you find also a lot of documentation and tutorials.
At the moment I am developing a demo for a customer, integrated with the Oracle OSB.
Hope to blog more about the product soon.
