Future plans
Due to the fact that shift2 can also be used as a library (as outlined in the README ), I would like to write a program that allows users to talk to eachother IRC style over a TCP port. This program would use either a pre-shared, or generated key to encode / decode messages on the fly.
If you are interested in helping out, or taking on this idea for yourself, send me an email.
