Currently, the binary release is free. Sources are subject to different
pricings. More info at http://www.vitanuova.com

BTW, the DIS (the VM on which Inferno is built), supports both RC and a
mark & sweep collector. 

The VM provides pointer-manipulation instructions which are RC aware and
others which are not. 

Programs could be compiled for this machine without using RCs.
