Broadcasting to terminals from kernelspace?

Hi,

Is there any easy-ish way to implement a wall-like functionality in a
kernel module? For example, if I wanted to load my hypothetical module,
could I get something similar to the following output?

stephen@icipher:~% insmod ./broadcaster.ko
Broadcast message from kernel module "broadcaster":
    I was loaded!

stephen@icipher:~%

Thanks in advance,
Stephen
