I feel inclined to agree, but in current market, the metaphor of zipper would not be appropriate. Choose and buy RTOS, say, VxWorks or LynxOS, RT linux or so. C/C++ toolchain would be available without other costs. Alas, Ada compiler would be *optional* with considerable additional cost. Zipper cannot be optional :-) -- Toshitaka KUMANO
