.	Related Project/Technology	Proposed by	Description	Votes
	Android	Carl Rosenberger	Google has launched the Android Developer Challenge with a total of $10 million of prize money for the best projects. We are collecting ideas for possible projects.	-
	Microsoft Sync Framework Provider for db4o	Luciano Di Cocco	Microsoft has just released a synchronization framework. A db4o provider would allow db4o to participate in synchronization tasks with any datasource supporting ADO.NET (e.g. SQL Server). Unlike dRS this solution won't need Hinernate to sync to/from relational datasources	5 votes (Vote!)
	Nuxeo 5	Stéfane Fermigier	Nuxeo Core: looking for developers that would like to extend the core with new kinds of document storages other than the JCR, for instance a RDBMS (via Hibernate), an OODBMS (like db4o) or an XML database, add application-level replication / synchronization, etc. For more information see this blog post	0 votes (Vote!)
	Merge Module	Carl Rosenberger	An object tree external merge module for db4o. See this post for more information	4 votes (Vote!)
	EclipseLink adapter	German Viscuso	EclipseLink is the successor of TopLink, now focusing on providing a standard and universal open source persistence framework for the Eclipse project.	0 votes (Vote!)
	Pluggable low level communication for Client/Server	Kaushal Shastri	e.g. overload OpenClient or OpenServer methods of the container to user a url reference (e.g OpenClient(http://....) or OpenServer(protocol== http, port = 80). For example a SOAP wrapper might do the trick still keeping the body of the SOAP message in binary format for efficiency. Even XML-RPC may be efficient enough for the purpose.	0 votes (Vote!)
	db4o XML database	Carl Rosenberger	Turn db4o into a pure XML database by writing a reflector layer that operates against XML (see this post)	1 votes (Vote!)
