I’ve recently released Zato 1.1 – this is an open-source Python-based ESB (Enterprise Service Bus) and app server for building middleware and backend systems of systems. It is licensed under LGPL.
I think it’s a very interesting alternative to already existing solutions in that area and a news item about it would be certainly interesting for programmers using all sort of dynamic programming languages, such as Python or Ruby.
In fact, this has been already covered in Linux-Magazin DE and Ubuntu’s Full Circle Magazine
If you’d like me to tell you more about it, please feel free to contact me using dsuch at zato.io
