Could be. And if so it would be a boon for developers using Google App Engine.

Some bloggers have speculated that Google may be following Microsoft's lead and creating something like the DLR to enhance development on the Google platform. The DLR is a Microsoft project to bring a set of services that run on top of the .Net CLR (Common Language Runtime) and provides language services for several different dynamic languages. The DLR has been used to implement dynamic languages like Python and Ruby on the .Net Framework—in the form of IronPython and IronRuby—and is a core element in Microsoft's push to enable the use of dynamic languages in the browser.

Microsoft's James Hamilton blogged on his speculation on a Google DLR look-alike.

The Microsoft database and development guru, and member of the company's Data Center Futures Team, said: "It’s hard to know for sure what is coming but the popular speculation is that Google will be announcing a dynamic language runtime with support for Python, JavaScript, and Java. A language runtime running on both server-side and client-side with support for a broad range of client devices including mobile phones would be pretty interesting."
