Can Eucalyptus be the "Lucene" of cloud computing?

Eucalyptus is an open source cloud platform which can be used to create private clouds. It came out of a research project at the Computer Science Department at the University of California, Santa Barbara. The good thing about it is that it has an open and modular architecture, which means it is perfect for experimenting with different kinds of innovations in cloud computing platform development.

Sounds like Lucene, the open source text search engine that with its extensible design became a vehicle for a lot of innovation in search - leading to innovations like Solr, Nutch, Hadoop, HDFS, etc.Whenever a platform is made open, and its design made modular, extensible - it becomes the hotbed of innovation. That happened with Unix, Linux, and is now happening with Android. Will Eucalyptus take cloud computing there?
