Hopefully the US government will do better than the awful AUSKEY system that the Australian Government designed. Every time I upgrade my PC or notebook, I have to download a ton of Java crud, not to mention certificates, in order to be able to use it, and even then I have constant browser issues with particular versions of Java or certificate chains being misconfigured.

Unfortunately, I have to use AUSKEY to transact on my business tax details etc., and just the sheer UX nightmare that it is makes an already detested task even harder to swallow.
