What Bernd said. Reading may be simpler, here you can store the meta-information from the start of the file in memory and then read entries as you go, ZipFile inside the zip package does something like this. When you consider writing you'll have to write metadata about all entries before you even start to write the first bytes of the first entry. Either you build up everything in memory or you use a temporary output. This is not without precedent in Compress, pack200 allows users to chose between two strategies that provide exactly those two options.
