As you may know, are working on making YaST functionality accessible via the web. With this we mean not only browser. The current prototype has two parts: a generic web service (REST like API) and a web browser client.
This is very early code. It is not fast, and the web client is not yet using all user interface possibilities that ajax gives, but there are we going :-).
If you are an experienced user, and you get it running, you may be interested in getting it running from source code by reading our development web page. Both the webservice and the webclient are rails applications. Developing modules is also easy! Just show up in irc (freenode) #yast.
