Script for comments

After admiring a club web page such as, say, http://tilde.club/~barnold/, you want to make a comment to say how wonderful it is.

In your account on club, you create a text file comment.txt saying "Love your page!". Then at a shell prompt you run

$ ~barnold/bin/make-comment comment.txt

which adds the contents of your comment.txt to a comment page, say http://tilde.club/~barnold/comments.html. Since you were logged in at club, your comment is automatically attributed to you.

Does such a thing already exist? If not, is there any show-stopper that makes it infeasible?

Thanks,
