Yes.

No, the pugin in only used for plugin-declarations: EMBED in
Netscape/Opera and OBJECT in IE.

As long as it's accessible to the VM - either downloadable or
installed - you can use it.

More people can use applets than can use ActiveX components. Also, the
size of ActiveX components (if we talk C++ or VB here) is larger that
for a Java applet of the same functionality (according to some
sources).

Note: For MSIE, any applet is also an ActiveX control.
