Limiting Incoming Messages

Is there a way to limit incoming messages?  

For instance if I message a buddy to check in, I am concerned about getting a few messages back (or more than a few if he is in a really good passive aggressive mood).   I doubt there is a way of blocking replies, but I thought I would ask this forum.

If blocking or limiting replies back isn't possible, do you think there is a way to send a message to a number I have (like Google Voice) that would forward it (either SMS or email) to my buddy?

I suppose I could also setup a dedicated twitter page...
