As I pointed out, you can have a bug on the sending end as well. And the TCP checksum is extremely weak, basically just sum of words--that's fine until you have a terribly noisy corrupt transport...

So yes, in a lot of circumstances it's overkill, but I prefer to be paranoid when a network is involved.
