Lemonade is a remote utility tool. (copy, paste and open browser) over TCP. For example, you use a Linux as a virtual machine on Windows host. You connect to Linux by SSH client(e.g. PuTTY). When you want to copy text of a file on Linux to Windows, what do you do? One solution is doing cat file.txt and drag displayed text. But this answer is NOT elegant! Because your hand leaves from the keyboard to use the mouse.
