ClipBoard Emulation

There are cases where I connect to a VNC server but I have no control over that server so things like clipboard sharing are disabled and I have no ability to change that.

On web VNC clients (like "novnc", for example), I noticed an extremely useful feature where you "paste clipboard" and it enters the text manually for you into the terminal....  It's not perfect for very long strings, but for short text like passwords and such or parameters or syntax that's too cumbersome to copy over by hand, it is great.

Couldn't this feature be easily implemented in the drop down menu in the VNC window?

Thanks
