What do you think about the following proposal: 1) Add a type converter which supports a conversion from InputStream -> ZipFile and from InputStream -> ZipInputStream 2) Implement a splitter which extract the (multiple) ZipEntry, add some header to each of them (name of the entry, number of entries, size, ...) and put them into its own exchange.
For the other way (create a zip archive which contain multiple entries), you could provide an Aggregator (AggregationStrategy) which work with ZipEntries...
