I don't understand what you mean? What is a module?

There is a web-based application (WAScreenshot) included with Seaside
that enables accessing the GUI of a headless image through the web. It
is a bit slow (it essentially just displays a screenshot) and not very
user-friendly (mouse clicks on the screenshot are forwarded to the
image) though.

If you use RemoteFrameBuffer (VNC) you are very likely tunneling
through an SSH connection anyway. I guess nobody wants to keep an
unencrypted VNC port open on their server.
