You name it and OCS can do it. I know that might be reaching a bit, but I've been looking into the new features that R2 will bring to the table, and it is really quite impressive. I've been working with OCS 2007 for about a year now, and while I've been impressed, there are some cases where I've had to say, "well, OCS really isn't a product for that arrangement," or, "it's still early in the product life-cycle, it'll get better." Now, most of those phrases are going to go away and will be replaced with comments like, "yes, OCS can do that, and that, too."
This is by no means an exhaustive list, but this is a quick start of the things to come with the new release. I garnished these points from watching a video here. There are a bunch more OCS 2007 R2 videos, and I can't wait until it hits RTM so I can install and play with it!
