web-based access to the shell?

[Ferindo Middleton Jr]

Is there a way to access the shell, of course securely using SSL, 
through a web browser. I was thinking that there would be a program 
already a part of fedora core packages or extras, or a combination of 
various different packages, that could implement  this.  Being able to 
access the shell through a  standard web browser  would be really 
convenient  and I'm sure  it been thought of before  and there already 
some open-source implementation of this.
