In my opinion, even if we do need SDP_PRANSWER (Cullen may have convinced me that there is a need for it :), I don't think it should have an implicit "recvonly" meaning. 

PRANSWER or ANSWER, I think we shall use the SDP direction attribute (or some other explicit elements) to indicate media direction.

Yes absolutely I have come across a number of scenarios in the US and in Europe where media is needed in the forward direction for DTMF input after receiving a 18x response and before the 200OK. IF I remember correctly calling FEDEX was actually one of the real life examples.
