Got word through my network (thanks, Rita) that Forterra is likely laying people off:  http://dusanwriter.com/index.php/2009/12/20/is-forterra-headed-for-acquisition-layoffs-reported/

Having used Forterra in a project within the past year and a half, I have to agree with the writer that Forterra’s issues are related to cost of software and services and a somewhat unstable platform.  Plus, as I said in my last post, virtual world technology is available as free or nearly free open-source.  Opensim, for instance, is open source and looks/acts a heck of a lot like Second Life.
