as you've found out by yourself, not streaming out the images to temp files hogs huge amounts of memory (and is therefore not an option). Your first item is actually the crucial point here: as our PPT import is just that, an import, we really have to fully read the file content. This is because our own, internal representation of the document content (the 'model') must be complete before anything can be displayed. There are currently no mechanisms to lazy-load only the first slide, and the remainder only on demand. Changing that would be quite some work, as it would require large refactorings to integrate PPT import more tightly with the drawing layer model.
