Holding on to the original stream and creating new readers for each section is one option, an other one could be to add a #reset method.
NeoCSVReader holds a one char buffer, so you could peek for something, just maybe. Then you could discover the section switches while parsing (a bit like #atEnd is used from #upToEnd, add a #atSectionEnd). But it all depends on your specific format.
