Mike Theroux has written a document about Ridl and his experience of implementing some part of it. See http://www.ccs.neu.edu/research/demeter/design-decisions/remote-invocation/RIDL. doc Based on Mike's analysis, it seems that we should rethink Ridl in terms of Demeter/Java. Ridl is intended for Java. Is Josh interested in taking on this project as soon as he is done with Cool? -- Karl
