MobileDataNow, a product that I’ve blogged about before, is now an open-source project. MobileDataNow started as a proprietary offering from FireTrust, and some time ago (late 2008/early 2009) was made available to the public. The source is available on Google Code.
MobileDataNow uses an OpenLaszlo front-end to allow you to configure data stores and mobile notifications. From the docs, it looks like it was upgraded to some edition of OL4.
