Ask HN: Using GoDaddy's domain broker service for expired domains?

There's a domain I'm interested in that appears to have already expired; its WHOIS information lists its status as `clientRenewProhibited`. Though the actual expiration is in a couple months, considering it was registered through GoDaddy, I have a feeling they will simply renew the domain themselves and then squat on it. When I go to register it now, GoDaddy claims it's taken, but they can use the "domain broker service" to help negotiate for it. Since the actual owner isn't in control anymore, I find this to be suspect.

Does anyone have experience using the GoDaddy Domain Broker Service successfully? Bonus points if you're using it on a domain that has already or is about to expire.
