StartSSL offers as many wildcard certs as you want for a low fixed yearly fee (50$)?
It will matter if StartCom is abused to print certificates for foreign domains. Even if your domain isn't targeted, browsers and OS vendors will probably react by invalidating all StartCom CA certs. That means no green bar.
So, I doubt they would treat StartSSL any worse than they treated China.
A friend of mine got validated and he send me signed and working wildcard cert with multiple domains a few days ago - so it's a real thing I believe.
