I had not heard about that legislation, so if you have any article names or links I'd love to read about it. (Plenty of talk and proposals, but nothing definitive.) It doesn't seem feasible, though, given the shear number of encryption programs and algorithms that currently exist with no backdoor 'skeleton keys' to be handed over. They'd all essentially have to be rewritten, but previous releases would still be unaffected.
As to knowing which may or may not have backdoors built in, it's nearly impossible to tell with proprietary software. Microsoft has strongly disputed claims stating that they have granted the US government backdoor access into Vista's Bitlocker, adding that they themselves do not have a secret entrance or method of decryption. That can't be easily proven one way or the other, but open-source offerings hold few secrets since anyone can view the source code and search for backdoors or other vulnerabilities. On that end see PGP/OpenPGP, for which there is reportedly no backdoor in existence.
