Calling a method (i.e. setConfig(), setVariable()) of the flash player (in

The ready event fires before your swf has loaded, which throws an error.

Unfortunately not. sIFR measures the element that's being replaced, then scales
the font to fit,
so unless the html font and the flash font are very similar, the sizes will be
different (and
difficult to predict).

There's actually already a text-resize plugin for jQuery, called jQEm:

Agreed, Klaus ... but Sam's not trying to get around it ;-)
He just wants alternate content to show when flash is blocked, rather than the

I had to do something similar recently. What I did was overload the css and

builds the inline css string.
For example:
