Bitcoin itself is too still in beta. These techs will probably never their beta states because they will never become a bug free full version.
There's no such thing as bug free software, except from some Hello World programs. Bitcoin will be out of beta when the devs will feel like there's enough features and solved problems to justify it. Still, Bitcoin's beta status is not the same as beta status of some other software, Bitcoin never had some closed private trials, if we don't count something that Satoshi might have been doing when he was still writing the code; and Bitcoin won't see a relaunch of the network when it will be out of beta.
