Simply put, MD5 is no longer strong enough for protecting secrets. It's just too easy to brute-force. SHA1 is ok for now, but it's days are numbered as well. I think it would be good to alter SHA1 (or something stronger) as an alternative to MD5, and I see no reason not to use a random salt instead of username.
If you aren't paying close enough attention to your database server tosee that someone is trying to brute force your MD5 password you have bigger problems.
