I think that with StarCraft Remastered coming out, and the features that were given to SC2 would also potentially be a good idea to be implemented into the SC:R System( at least taken into consideration ), I presume that all of the battle.net Servers aside from Fish will have a Clan system that is similar to how the Korean Clans have it on the Fish server. If you are unaware, on the Fish server, there are clan functions built into the server. ( /clan message, etc. ), A auto clan greet when you join the channel / Info on league matches / clan wars etc. ).
On the Regular SC BW Servers right now if you attempt to type /c msg or /clan msg it tells you to "type /help clans for more info", so I imagine Blizzard will be adding Clan functions to SC:R like they did in SC2 / similar to how they have it on Fish, otherwise that wouldn't be built into the System.
On a side note, Automated Tournaments in BW I think would be a much bigger success than they were in SC2, what do you guys think? Come on Pete, hook it up! Hype for Tomorrow!!!
