Most of those sites you probably wouldn't want to show a client or management anyway because not much has been invested in their customization.
They why are they on the front page? Perhaps a more management friendly strategy would be to have a 'showcase' on the front page, and then somewhere else a 'list of OFBiz users' with a disclaimer. You also say that it's not worth tossing a site because it's down, and that's reasonable. However, the cumulative effect of a number of sites not being available looks bad. -- David N.
