Automate web login for low vision user

I am looking for a way to use Automator to enter a user name and password for a user who has limited vision. I need to enter the text into the two fields so that he can log in. He uses the zoom feature but the magnification has to be set so high it is hard for him to locate the text box and then locate the correct keys the pass phrases. At 90 I’m just glad he is interested in using the computer at all.

Is there a way to accomplish this in OS X Leopard using Automator?

I would try to use the new Safari 5 and write a quick extensions that, when your user opens this pages, the user name field and password are completed automatically by JavaScript. Additionally the login button can be clicked also.

Safari 5 promises to have extensions developed very easily.
