uinput-mapper maps input devices to new virtual input devices, using (as implied by the name /dev/uinput[1]).
[1] Or /dev/input/uinput depending on the OS.
Configuration is done in Python; examples and other information can be found on the project website: http://hetgrotebos.org/wiki/uinput-mapper
None that I am aware of, but if you find some please drop me a mail at http://wizzup.org. (You can find my email address there)
The configuration format is considered unstable (that is: open for changes) until I am satisfied with it. Although I currently have no plans to change it.
uinput-mapper is more than just a input mapper. It allows transparent input redirection over the network and also has a nice python API for input and uinput on Linux.
