You can always catch and tune form updates in javascript.
With javascript it is also possible to just submit the data without
touching the displayed data at all or just update a partial page.

Ajax is a browser thing.
Nut/OS already has everything you need.
On EIR you only need to add application related CGI functions.
E.g. add a CGI which only delivers the table with the radio station list
and not a full HTML page.
Then use Javascript/Ajax to do do the CGI request and fill the radio
station block in the page with the CGI result.
This is just a simple example - expirienced Javascript programmers
often ask for plain XML data instead of HTML fomated tables.
This way they can easily modify the result and use the plain data
almost everywhere.
