In many states, recording someone without their knowledge is a crime. Any experts on those laws here?

I believe in Txas and New York only oneee party to the conversation needs to be aware that the call is being taped. It varies by state.

My understanding: you can tape it provided one of the two parties involved knows that they are being taped.

However, broadcasting or even disseminating the contents of such a conversation usually is illegal.

There is a federal law that forbids broacasting any telephone call where both parties are not aware of the recording or broadcasting. Some states allow recording of phone conversations with only one person's knowledge, but the FCC says you can't broadcast it without the knowledge of all parties.
