hi All

We want to implement our company Intranet (currently using XOOPS) on
Google Apps Sites (we are a Google Apps Premier customer).

We have a lot of online forms on our Intranet.   Forms like expense
reimbursement where our staff enter their expenses and attach receipts
to the form and then submit the form.  The form data will then be
email to our accounting staff with download links to the receipts
(which are stored our webserver).

It is not possible to implement this in Google Apps Sites, and so we
are thinking of creating an application on Google App Engine and then
packaging it into a Gadget and inserting the Gadget into a Dashboard
in Google Apps Sites.   It seems that this is the only way to
incorporate a Google App Engine application into Google Apps Sites,
i.e. via Google Gadget.

But it seems like there is not flat file system on GAE to store the
uploaded file.  And the file has to be stored as a blogtype entry in
Google datastore.   But Google Datastore has a limit of 1MB per
entry.   Our users sometimes upload files as big as 100MB (for CAD
files).   Also, after storing the file in the Datastore, we need it to
be immediately available for download as link in the form email
notification.    For example, after our staff submit  the expense
reimbursement form, an email will be sent to our accounting staff and
the email will contain a link to the receipt/invoice file uploaded,
and the accounting staff can download the receipt file -- this is what
we are doing now using our Xoops Intranet.

I got the information that there's no flat file storing in GAE and
that there is a 1MB limit on DataStore entries from this site:

Thank you.
