SCO has been much maligned to the point that it's easy to forget that there a real people who work there, just trying to do their jobs. Being from Utah, where SCO is located, I happen to know a few of them.
This story on SCO's mobile push technology is one I'm familiar with because the engineer behind it is a good friend. SCO bought his company and the technology a few years ago. I saw a demo at my monthly CTO breakfast in April and was pretty impressed.
The most impressive thing to me was not the specific push product featured in the article, but the technology that underpins it, something SCO calls Me, Inc. Mobile phones are horrible to develop for because everyone has a different OS, language support, and so on. Me, Inc. is a level playing field that provides a single development and run-time environment regardless of mobile phone.
