It is possible, but it hasn't been released, so it depends very much on how comfortable you are with learning from the code and the samples. The reference material does not include this information. There is now a reasonable set of examples, all of which demonstrate the use of the new configuration options and can be easily run from within the codebase using the maven jetty plugin. So it is actually easier to try out the samples by checking out the code than it is to download a distribution, as you don't have to do any deployment or container configuration. Everything should already be set up, including SSL support.
So install maven 2.0.8 and download the code using subversion:
svn co http://acegisecurity.svn.sourceforge.net/svnroot/acegisecurity/spring-security/trunk/
from the project root directory. If that goes smoothly, change directory to samples/tutorial and run
which should run the basic sample app. You can base your own app on that and expand it according to your requirements.
