Designing network protocols by hand is a costly and sometimes troublesome work. This C# library implements a generic network protocol that transports the events object creation, object destruction and the change of a property of one of those objects. It also has facilities to observe the objects for property changes. In sum, the properties of objects that are taken care of by the library are automatically kept in sync. The only requirement to the objects is that they notify the modification of their properties, similiar to what WPF requires from a (typical) view model.

Java Remote Method Call provides a Framework for remote method invocation on Java objects which solves the limitations of Java RMI. It provides a way for bidirectional communication of object states, between Client and Server.

srtools is a set of simple remote tools. the main two to mention: simple rdist distributes files or commands across hosts. srdist(1) understands rcs(1) files and host based files. there are several other tools see README. rcs tools has a few things , like "late-checkins" to check for files that one forgot to check in an dorev to force check in / do easy check in (avoiding complicated options). host based files is a way to allow hosts to distribute all files without clobbering host specific files. and with that ... srtools(1) makes partially synchronizng hosts easy. Also can be a far easier way to do incremental or nightly backups. Also an easy way to have multiple hosts interact. README is visible on file download page EXAMPLE: $rcssrdist file (file was broadcased to default hosts list that are up. if a rcs pair existed it was taken care of. existence of directory on other hosts was checked (common mistakes checked)

PYBAG implements a portable bag and is intended for fast synchronization and backup. It lets you use a portable digital storage device to carry your electronic documents similar to the way you can use a bag to carry paper documents. You can synchronize the bag with your original files easily. If a synchronization conflict occurs, it will be reported. You can specify rules for automatic conflict resolution. With PYBAG, you can backup files and synchronize any changes made to the original files with the bag. The synchronization process will only copy changed files. The program is cross-platform and independent from the OS and file system. You may easily synchronize files between Windows and Linux, for example. Symbolic links are supported on all systems (if the OS or file system does not support symlinks, then they are emulated). This program has a GUI and a command line interface.
