Heh... yes those are many more excellent examples. Also consider if your 
ISP is the bad guy, or your ISP themselves got hacked... so it becomes 
even more trivial to do MITM. The important thing to know is that these 
are not difficult to do, so the question isn't so much how to do MITM 
attack... it can be done... we have to deal with it :)
