Just curious: how well is photoshop pdf today? It used to be non valid pdf 
for viewers ...

Also: watch out when saving-as-pdf in illustrator (actually pdf is kind of 
the native illustrator format since v 9): you get everything twice: once as 
edit stream (moved some 7000 points in the margin) and as preview (as well 
as a bunch of ps code in a stream). Saving ai files in minimal pdf with 
proper boundingbox was discussed recently with adobe (tex-adobe meeting a 
couple of weeks ago).

also, that text stream goes into a separate page stream (a page can have 
multiple streams).
