Great - that is most helpful :-)

Right - so the custom properties are saved in a separate stream either:
\05SummaryInformation and/or \05DocumentSummaryInformation - and are in
some magic MS/OLE file format. You can prolly chase some of this down
from here:

Though there are a lot of links to follow. AFAIR each of Word, Excel
and (particularly) PPT use a slightly different version of this perhaps
different stream names.
One of our bigger missing .ppt export features used to be not exporting
slide names - which (AFAIR) were stored in streams like this too - it'd
be great to fix that: it sucks to loose slide name information.

Yep - so to find the related code:
/g grep 'SummaryInformation"'
Will show you some fertile places to read (ignore the binfilter stuff).
Hope that helps ! :-)
ATB,
