Lately I wrote a small ssh client that allows you to take your configuration files (such as .bashrc, .vimrc) to the remote easily. Got too frustrated copying those manually as I have quite many remotes I work with and also because I like to tune my configs constantly. Also I have some ideas for further development once I have time for that.
