MiniIM is multi-protocol instant messaging client. It is based on J2ME and thus targets the MIDP2 supported platforms (commonly found in the mobile devices). It is inspired by the popular Pidgin (Gaim) program. The design is concentrated on the protocol level abstraction and an easy way to integrate new protocol implementations. The interface design is unaware of the underlying protocols.
SyWiCo is a tool for managing concurrent modifications of shared files between unconnected computers. It can be used as a synchronization tool relying on email. Its main design goal was for synchronizing the source code by email between developers, when the use of a source control software is not possible. The communication is stateless and reduced to a very small number of messages, typically 2 or 4. It does not create any files in the directories that it synchronizes, and leaves one participant free from dealing with merging and conflict resolution. This is not a tool to replace source control programs, as it provides no versioning.
