IBM recently announced a official release of WebSphere sMash, a licensed version of Project Zero. Zero is a CDCD (Community based commercial development) project but the stable and licensed (IBM) version of it is sMash.
Also Project Zero is based on REpresentational State Transfer (REST). The good thing about it is the rapid development of web applications. This is actually intended for situational apps which are needed immediately. And after you developed a applications, you don't need the application server, you applications itself is a server .. umm sounds interesting.
But this is not it yet, it supports all the web 2.0 stuff like Ajax, Feeds, Json and all. Pretty good security support is also there LDAP, file based, openID.
If you are a web developer and you want to get your hands dirty in web 2.0, you gotta check out this one. Nice work! (www.projectzero.org).
