Is it possible to log server chat to a file?

I was just wondering if it's possible to log whenever someone chats in the game into a file?

for example

Someone says "Hello World!"
and in a file it adds "So and so said: Hello World!"

In ComputerCraft no it is not possible, however there are people who have created peripheral mods to give blocks to do this however.

to just list a few mods that add a Chat Box peripheral:
MiscPeripherals (broken, don't suggest using this)
MoarPeripherals (its not a shameless plug when I say other peoples mods okay :P/> )
Computronics
