    <Paragraph position="0"> In this paper we consider how to scale up dialogue protocols to multilogue, settings with multiple conversationalists. We have extracted two benchmarks, MLDSA and MAG, to evaluate scaled up protocols based on the long distance resolution possibilities of NSUs in dialogue and multilogue in the BNC. MLDSA, the requirement that multilogue protocols license long distance short answers, derives from the statistically significant increase in frequency of long distance short answers in multilogue as opposed to dialogue. MAG, the requirement that multilogue protocols enforce adjacency of acceptance and grounding interaction, derives from the overwhelming locality of acceptance/grounding interaction in multilogue, as in dialogue. In light of these benchmarks, we then consider three possible transformations to dialogue protocols formulated within an issue-based approach to dialogue management. Each transformation can be intuited as adding roles that correspond to distinct categories of an audience originally suggested by Goffman. The three transformations would appear to be complementary--it seems reasonable to assume that application of all three (in some formulation) will be needed for wide coverage of multilogue. MLDSA and MAG can be fulfilled within an approach that combines the Add Side Participants transformation on protocols with an independently motivated modification of the structure of QUD from a canonical stack to a stack where maximality is conditioned by issue dependence.</Paragraph>
    <Paragraph position="1"> With respect to long distance short answers our account licences their occurrence in dialogue, as in multilogue. We offer a pragmatic account for their low frequency in dialogue, which indeed generalizes to explain a statistically significant correlation we observe between their increased incidence and increasing active participant size. We plan to carry out more detailed work, both corpus-based and experimental, in order to evaluate the status of MAG and, correspondingly to assess just how local acceptance and grounding interaction really are.</Paragraph>
    <Paragraph position="2"> We also intend to implement multilogue protocols in CLARIE so it can simulate multilogue. We will then evaluate its ability to process NSUs from the BNC.</Paragraph>
