Web Hosts & Terms of Service

I was having a poke around at various hosting companies today to see what was on offer, and having a look through there 'terms of service'.

Although I've not found a better host than the one I'm with, the terms of service I found at Easy Internet Solutions were quite remarkable. Under the heading 'Direct Violation Examples' was "Running of software than listens on any TCP/UDP port".

Does that not pose a slight problem for a web host not allowing IIS/Apache or any other web service to run on there servers?

For the curious it's near the end there AUP (or was on 3rd Feb, 2007).
