Yahoo! introduces mobile XForms

"Admittedly, their marketing folks wouldn't describe it that way, but  
essentially that's what was announced today. (documentation in PDF format,  
closely related to what-used-to-be Konfabulator tech) The press release  
talks about reaching "billions" of mobile consumers; even if you don't put  
too much emphasis on press releases (you shouldn't) it's still talking  
about serious use of and commitment to XForms technology."
