HeyGuys,
This is not something we are likely to do, as is has privacy implications. As IPs are not per-user, you reduce the security of every user on a particular IP address to the lowest denominator, regardless of what data you expose to external users.
For example, if Alice and Bob are on the same IP address (living on a college campus), they would share the same external facing “hash.”
Now, if Bob is dumb, and has his info exposed through skype, or whatever means, a malicious user now knows that Alice is connected through the same IP, and might know her address, her IP, or other sensitive information.
For this reason, we are not planning on implementing this feature, but are always open to suggestion!
