As promised, here is the pdf file of Ion Mironescu about using squeak 
seaside as a SCADA (Supervisory Control And Data Acquisition ) tool 
written in squeak and using seaside for the HMI.

The code is open source but not published yet.

The file is named "object oriented framework for a scada hmi" from I. 
Mironescu. File is ok but pictures are not perfect, anyway it's 
readable. You can download it here: 

I think it deserves a sreenshot for the user section of seaside.st ;)

Thanks Ion :)

> He made an open-source SCADA tool (/Supervisory Control And Data 
> Acquisition /http://en.wikipedia.org/wiki/SCADA) based on seaside and

> for the backend, and SVG to get a fancy user interface. Machine data 
> are generated by a PLC proxy (written in C++) and written in GOODS. 
> The web interface is updated  (by comet/asteroid). The web interface 
> also allows to update the database.
> I found the whole app very interesting especially for the whole 
> integration aspect. As far as I know, his apps works well. He has only 
> cache problem leading to some update problems ("at data production 
> rate (2s-1), the browser began to miss update events  or to delay
