There’s an excellent summary by Ethan Marcotte of the workarounds by Microsoft and other vendors to the IE changes mandated by the Eolas ruling. This is a particularly evil mod that MS are making to IE 6 to cripple clean use of plugins (cf RealOne, Macromedia Flash, etc.) without changing any code involving EMBED, OBJECT or APPLET tags. You can probably guess how evil this is just from the tags involved.
