"Many people still want to use their existing Adobe tools for developing ads, and retooling to support a single platform seems silly," according to Smokescreen's blog.
Smokescreen does need up-to-date browsers, and the demo advertisements works on Firefox 3.6, Chrome 5, Safari 4 and the mobile version of Safari. It won't run yet on Microsoft's Internet Explorer 9 although it "looks promising," according to developers. There are "known, fixable" issues with Opera 10.5.
Smokescreen's code will soon be released under an open-source license. Its developers have posted a preview along with demos. Low-cost support and service options will eventually be made available, according to Smokescreen's blog.
A test of Smokescreen's demos on an iPhone showed that the more complex the animation, the slower the advertisement rendered. On a desktop computer, the performance was faster.
