I have been able to generate working StormOS Flash ISO that appears to be fully functional (if you don't mind getting your hands dirty - that is) so I think it's getting close. If all goes to plan StormOS Flash Pre-Alpha will be ready in ~2 weeks. I'm not sure I have enough space/bandwidth to host the ISO though so if somebody else could do that for me that would be very much appreciated. In the meantime I'll speak to RootBSD about increasing my storage.
For now I'll leave you with some screenshots taken from some of my development ISOs.
