They could be on the road or just plain busy. How about in the middle of negotiations. setting parameters, benchmarks.... you know, if we achieve this then.... and if we go further....., sizing up the interest now and what it could bring. How about meeting with the doctors that have already concluded their testing and are reviewing results, getting an even more detailed idea? Hope and would think that's what's up and not in front of a computer. Wouldn't surprise me if we got it later after they're finished with whatever they're doing.
