More barriers being broken

db4objects - native Java and .NET open source object database engine: "'With Version 5, db4objects is pushing the seamless object-oriented development experience even further,' says Stephen O'Grady, senior analyst at Redmonk. 'When developers are not required to transition out of an object oriented environment and the language of their choice, they're likely to be far more productive. Consequently, several vendors - including Microsoft with its LINQ project - are seeking to break down the barriers between non-native APIs and the programming language on top of it, by allowing querying in native language - an approach that could become popular to access databases from OO programming environments.'"

Looks interesting, but unfortunately there doesn't seem to be support for the new, intersting, dynamic languages.
