Some IRC networks, like Freenode for example, allow registered users to cloak their IP address with an ID that represents a project they contribute to.
Would any of you find it useful for users with some amount of reputation could apply for stackexchange-affiliated hostmask? Something like:
stackexchange/<site's bottom level domain>/<site-username>
/whois on a cloaked user affiliated with 'Musical Practice & Performance' would then return
stackexchange/music in place of their IP address.
