--- Comment #1 from PJ Fanning <fannin...@yahoo.com> ---
I have a sample of what I'd like to change in
https://github.com/pjfanning/poi/commit/72f0ada28f17b0079d296fa6dbc98d3b76b058a3

I can add test cases to demonstrate the ability to plug in custom temp file
implementations to override the use of simple temp files.
By subclassing this version of SXSSFWorkbook, developers can replace the temp
file behaviour in write(OutputStream stream) with a custom ZipEntrySource (see
org.apache.poi.poifs.crypt.TestSecureTempZip) before calling injectData.
createSheetDataWriter() can be overriden to return a subclass of
SheetDataWriter that overrides the decorateInputStream snd decorateOutputStream
methods I've added.
