I got my OLS paper finished last night. I put it on the UML site as both TeX
(http://user-mode-linux.sourceforge.net/ols2001.tex) and HTML
It provides an overview of the internal design and implementation of UML, the possible applications for it and the future. This is similar to the ALS paper, except that it's more up-to-date and I rewrote it (rather than copying from the ALS paper) so it will emphasize different things.
