webapps= GData + st plug-in?

Hi,
Apart from Seaside and Aida/web, is there anyone thinking of Smalltalk
browser plug-in apps using free Google services like Google
Spreadsheets as database, through GData API?

I am interested in GData API in VW, which seems to support Firefox
plug-ins. Is there any code examples for this?
Thanks in advance.

Best regards,
Jim G
