How Can I Inject Code To All Pages Viewed

We require the ability to be able to inject code into all pages that
people view. There are a number of requirements. I am hoping there
might be a catch all that will allow us to do what we need.


Firstly once people load up IE. I would like a banner to be displayed
at the top of ie reminding people of internet use guidelines. I would
like this to be visable at all times on all pages.

The second part is that I would like to inject code into all pages that
have shockwave. The injection of code would either hide or show flash
but in a PAUSED static state (ie no motion)

Not being a firefox guru, I understand that this is the kind of thing
people are doing with Monkeyscripts. However as a corp I cannot get
away from using IE because of the services we use.
