Remote Mouse netcat (/dev/input/mice)

I was playing around with nc and I'm discovering how powerful and versatile this tool is. I was wondering how the file /dev/input/mice works because when I do cat /dev/input/mice you see the output, but I am not sure how to play with that. I have tried an echo "blablabla" > /dev/input/mice thought it was going to change my mouse coords but didn't do anything. I have seen in a post that you can have a remote mouse with netcat (not sure where I saw it) So, If I can take the write from /dev/input/mice in a remote PC to a server listening, writing it to his dev/input/mice ¿? My idea is: Server : nc -l -p 6000 > /dev/input/mice Client : nc 6000 < /dev/input/mice I think that that wouldn't work, so does anyone knows how to perform this and explain it a little bit¿? Thank you in advance
