If you have not heard of Bioclipse then check it out. This is an amazing project and it is another great proof point for how valuable Eclipse is in the Rich Client Platform space.
Bioclipse is based on the Eclipse Rich Client Platform (RCP) which means that Bioclipse inherits a state-of-the-art plugin architecture, functionality, and visual interfaces from Eclipse, such as help system, software updates, preferences, cross-platform deployment etc.
Bioclipse provides advanced functionality in fields such as cheminformatics, bioinformatics, semantic web, spectrum analysis, drug discovery, safety assessment, and general chemistry education. – link
