I've OCR'd Saltzer's paper. It's available temporarily (in MS Word format) at http://sirac.inrialpes.fr/~marangoz/tmp/Saltzer.zip Since there may be legal problems with LNCS, I will disable the link shortly (so those of you who have not received a copy and are interested in reading it, please grab it quickly) If prof. Saltzer agrees (and if he can, legally) put it on his web page, I guess that the paper will show up at http://mit.edu/saltzer/ Jeremy, could you please check this with prof. Saltzer? (This version might need some corrections due to the OCR process, despite that I've made a significant effort to clean it up) -- Vladimir MARANGOZOV | Vladimir.Marangozov@inrialpes.fr http://sirac.inrialpes.fr/~marangoz | tel:(+33-4)76615277 fax:76615252
