The goal of HTML5 is that all browsers and platforms should be able to
display all web pages, without dependence on any particular software
vendor.  If a company like Adobe writes a framework using
cross-browser, cross-platform, openly specified APIs, we're in a far

toolkits that use HTML5 features.  Or do you have any suggestions to
stop it?
