A few comments on the foils. Foil 7 ("What we are not doing..."): One could say that when the DTF picks a protocol from the lists supplied by source/sink it is doing a primitive form of protocol negotiation. I do not see it as part of bandwidth negotiation. the "or" in this bullet is wrong. It should either be "and" or the two parts should be separate bullets (better) Foil 8 (DEPR). I would replace "YOU" with something like "DTI instance". Mario's comment about security has opened an interesting question: is there a security issue in passing DEPRs around if they contain authentication information? I can see one but it may be the same as my ability to disclose information that I have access to to a bad guy. This needs further thought. Foil 9 ("Where do DEPRS come from"). See my note from last week. I do not think that DMI should specify where they come from but I do think that we have an obligation to suggest what data services need to supply. This may be something that OGSA Data needs to add to its architecture document. Foil 10 ("DTF"). I would be careful about "best" in the first bullet. I would rather say that the DTF just picks one. "Best" has far too many dimensions and they are out of scope for DMI. "Negotiaste" -> "negotiate". I agree with Mario that the future items may end up outside of DMI. But I think that DMI is the logical place where these issues should first be considered even if DMI decides to push them to some other part of the architecture. Foil 11 ("DTI") I agree with Mario - we should include the state diagram.
