Yes, those lca2005 papers are mostly available
Martin and Mikal jumped the gun slightly and have mentioned that the papers from the conference are available. I'm actually in the final stages of extracting the last remaining ones from a few speakers who haven't coughed up yet (you know who you are).
I was suggesting Steven hold off announcing to lca-announce until such time as the majority of the papers were up, so people wouldn't have to keep checking back for the one paper that wasn't there yet, but was wanted.
Oh, and while you can browse at http://lca2005.linux.org.au/Papers, the papers are also linked in from the conference program pages, which may make finding a specific paper easier.
