Well, Bert Dempsey had a position at  UNC's School of Information and 
Library Science, but he wasn't doing transport stuff (might startle the

 This ties in to an interesting counterfactual; during the late 90s bubble 
the telecom sector massively over-invested in bandwidth; as a result, the 
relative cost of bandwidth compared to other factors was seriously 
depressed.  The counterfactual question: how would protocol design have 
been differed if bandwidth had not been underpriced?  Would SOAP exist in 
its current form?

What about if the bandwidth over-supply had occurred in the mid 80s; would 
OSI application protocols have had more success, or were they inherently 
doomed the moment the first session layer draft was printed?


1) Does anybody have a copy of the last HOSTS.TXT file? (or at least, the 
last one that had 10.* hosts in it).  What about a zone file for .arpa?

2) I think I've asked this before, but does anybody have a working Fuzzball 
for sale;if not, what about a free-standing LSI-11 that could be fuzzed up? 
I'd also be interested in a working Lisp Machine.  Yes, it would cheaper 
for me to just buy a new fan heater before the winter, but  it's history, 
dammit :-)
