I'm not convinced that includes the ISP themselves.

"a person intercepts a communication in the course of its transmission 
by means of a telecommunication system if, and only if, he
[does certain things]
as to make some or all of the contents of the communication available, 
while being transmitted, to a person other than the sender or intended 
recipient of the communication."

If I'm the one doing the certain things, does this wording include the 
case of making the contents available to myself? To me, the natural 
interpretation of the words would exclude myself, but I'm not going to 
swear that hasn't been case law (in respect of some other act) that has 
interpreted this wording one way or the other.

I believe there's two separate issues here. One relates to a 
hypothetical one-man ISP: if he looks at content as it goes through his 
network, is he intercepting within the meaning of the Act? As argued 
above, I think not. The second relates to a real ISP: is an ISP member 
of staff a separate person from the ISP itself? Again, I would have 
thought not.

On the other hand, 3(3) uses the words "by or on behalf of" while 2(2) 
doesn't. Does that make a difference?
