OpenDMTP (Open Device Monitoring and Tracking Protocol) is a highly configurable and extensible protocol for communicating with mobile devices over high-latency/low-bandwidth networks. The protocol is particularly geared towards the transmission of GPS base location information and includes a full-featured reference implementation showcasing its capabilities.
Synapse is an ESB engine and XML router built completely on open standards. It is a mediation framework for XML messages and Web services that allows messages flowing through, into, or out of an organization to be mediated, including aspects such as logging, service lookup, performance mediation, versioning, failover, monitoring, fault management, and tracing.
WeOCR is a platform for Web-enabled OCR (Optical Character Reader/Recognition) systems. It enables people to use character recognition over networks. A WeOCR server receives document images from users, recognizes text in the images, and returns recognition results to the users. WeOCR does not have its own character recognition engine. Instead, it is intended to accommodate various existing character recognition engines.

Cosmo provides Atom feeds for shared calendars, so you can track updates in your favorite feed reader and integrate your calendar into your Web site or blog.
The Privilege Separation patches for Apache HTTPD and 'mod_dav' address the problem that an Apache WebDAV server can only write files as the non-privileged Web server user (usually something like 'nobody' or 'www'). The patches address this shortcoming in a secure way by adding privilege separation to the Apache Web server (conceptually similar to SSH privilege separation). A privilege-separated Apache can be used to provide secure WebDAV write access to ~user directories and allow the use of per-user Unix quotas. When combined with mod_ssl, it provides a convenient and secure remote file serving system, as WebDAV clients are seamlessly integrated into both Windows and Mac OS X.
mod_athena is an Apache-based application load balancer for large systems. It allows the HTTP server to act as a load balancer either internally to Apache's own mod_proxy (for reverse proxying), or externally to machines querying it. Arbitrary statistics are sent to the engine via a simple GET plus query-string interface, from which it will then make decisions based on chosen algorithms.
Extended Virtual Synchrony for Java is a pure Java implementation of the totem single-ring protocol, which provides process group membership and reliable multicast with totally ordered messages. Because of its token-based design, this protocol is unique in achieving effective flow control, and is ideal for implementing replication in small clusters.
