Hi Iuri,
As Victor pointed to you there is a Live-CD running dotLRN OpenACS portal based on Knoppix. The live-CD is ready to use and you could change its contents and even install only OpenACS or a customized version you have.
Take a look at http://e-lane.org/pub/tutorial.html to go into details. It is easy and very fun. I think it could be a good solution for your concerns. You could change contents of the live-CD for example to put into OpenACS/dotLRN presentations and other informations you want to use in conferences or seminars
