Once a completed Haiku is put out to press, interest in this operating system is going to greatly increase (although Glass Elevator is something that I really look forward to).
However, in the meantime between the release of Haiku R1 and the beginning of Glass Elevator development, I'm hypothesizing that there will be people who are interested in redistributing their own version of Haiku, just like how there are so many Linux and BSD distributions (300+, according to Wikipedia). Alot of them will be LiveCD/LiveUSB-based distros, which has become obligatory in almost every Unix-like system (hell, there's even a LiveCD for AROS, the Amiga Research Operating System).
