Oxy-Propane Cutting

We know of oxypropane cutting like this - https://www.youtube.com/watch?v=Uo4w8A8oYkw - but can we also use wood gas for oxy-woodgas cutting? How about 6" PVC pipe for gas storage as a battery of 20' long PVC tubes? The oxy-woodgas is exciting from the local resource perspective. Would we have to compress the wood gas to say 20 PSI so it has enough pressure to run a torch - or can we run the gas right out of the gasifier? The good news on oxyfuel is that the oxygen does most of the lancing, so the key is just getting the metal hot enough. One could cut metal literally only on the oxygen if the steel is really hot.
