Q:

Document management using Plone4

I'm interested in making a document management system from Plone 4. 
I need pointers to a way to integrate FlexPaper and a way for asynchroneous document transformation using existing tools like SWFTools, Ghostscript, ImageMagick, Batik etc..
Thank you for any pointers you can give me.

A:

Plone 4 is an excellent choice. We've been using it as a document management system internally and for a number of high profile clients. The main selling points are:

Blobs are stored on the filesystem (not in the database);
OpenOffice, MS Office, PDF documents are indexed and their content searchable;
Fine grained ACLs;
Workflows.

Regarding your points:

http://plone.org/products/wc.pageturner for Flexpaper integration (we found that simply embedding the pdf, using Acrobat's plugin, worked fine too);
Wiki style content editing is supported natively (via Wicked);
Data lists can be implemented with a custom content-type, using DataGridField( http://plone.org/products/datagridfield ).

Other advantages:

PloneFormGen, now with AJAX quick-edit ( http://plone.org/products/ploneformgen )
Plomino, for TTW "Domino" style app creation ( http://www.plomino.net )
WebDAV and XML-RPC;
Content rules;
User subscription to content and email notifications (see http://plone.org/products/cmfnotification );
Can be installed as multi-headed, fully redundant system using ZEO and RelStorage (ZODB encapsulation in a RDBMS datastore backend, like MySQL, Postgres or Oracle),
