Apart from the fact that I a dedicated anti-ms person (for moral reasons   
:) I was going to make a comment along these lines... ActiveX seems   
designed to be used on an intranet or somesuch where the security   
controls imposed by most plug-ins becomes oppressive... or be used to run   
software written by trusted/reputable companies (sorry, are there any   
trusted large software companies?)... enter the age of disposable   
programming

As a class of software designed to run on a single platform of machines   
in an internal network, discussion of ActiveX is perhaps off-thread for   
the www-newsgroup ;)

Unless anyone knows anything about the keys that pieces of ActiveX are   
signed with... can they be forged... who can give out signatures... can   
the web-servers of trusted hosts be broken into and the trusted bits of   
software replaced with wooden horses...?

Which part do people find the most impressive? -
that the Win95 shutdown API works as documented
or that all these security experts are downloading and running
software designed to do something they don't want?

How does this control differ from an HTML page that tells
readers to turn the power switch off?
