AVIM website is going down for a few months due to severe time shortage in Hieu's land. Z Corporate Community - ZCOCO (and a very demanding & needy girlfriend) are taking over everything.
AVIM is still an active project however and new releases will be uploaded as soon as they are ready/needed. I repeat, AVIM is still an **active** project, don't let any fool tell you otherwise.
AVIM demo is available at: http://rhos.sf.net/pro/himtest.html
Main AVIM project page where you can download the software is located at: http://sourceforge.net/projects/rhos
