I could provide a virtualized ports build environment based on poudriere that would allow you/me to create (say binary only) packages for all the supported FreeBSD major branches. To begin with let’s say for arch i386 and amd64. This could all be achieved in one single VM. I could create the initial setup that would enable you (or me if you like) to create current packages. I could then create official FreeBSD ports that would make use of those binary packages. It could even be something similar to java where the user will have to login to your site and download the binary packages manually. Please contact me off list via e-Mail if you’re interested.
