Just addressing the general question, since this gets asked from time 
to time.  E-Prime runs on E-Basic, which in turn is a dialect of 
Microsoft VisualBasic, which in turn is a rather full-fledged 
programming language that can in principle do just about anything 
that can be programmed with a computer.  So in general, yes, whatever 
you want to do, in principle EP can do it.  Of course, in practice it 
may not be easy, and other programming tools may work better for 
specific tasks.

>If it is a possibility does anyone have any idea where to start?

I have never used EP with an eyetracker, so I cannot help you there, 
just wanted to address the general question.
