D:GameVFS is a minimalist virtual filesystem library for the D programming language oriented at game developers. It provides an easy-to-use API for filesystem-independent file/directory manipulation. It supports basic VFS functionality. Files and directories can be created, read, and written, but not deleted. There are no security features (e.g., D:GameVFS can't handle a situation in which a file it's working with is deleted outside the program).
Overthere is a Java library to manipulate files and execute processes on remote hosts, i.e. do stuff "over there". It was built for and is used in the XebiaLabs deployment automation product Deployit as a way to perform tasks on remote hosts, e.g. copy configuration files, install EAR files, or restart Web servers. Another way of looking at it is to say that Overthere gives you java.io.File and java.lang.Process as they should have been: as interfaces, created by a factory and extensible through an SPI mechanism.
