The Lotusphere session slides can be downloaded. I have written some code that will go and grab the 365MB of PDFs. There are 140 files. You need to grab the Genii software session db then add this agent code.

Grab the session database from lotusphere 2011 session here.

Then make a copy, then use the designer to add this code into an agent initialise

' NB You do need a lotusphere 2011 id and password.
