Hey guys,
There were no hits on the demo system and updating it every time there was a svn commit was a pain, hence I removed it. Anyways, I'll upload a demo version on my hp and share the link so that those interested can test it.
Regarding the File upload module, we're using a AJAX File Uploader module which is pretty cool and does a lot of things simultaneously such as passing file's metadata etc. And given our design, we have closely coupled it with our codebase. We can definitely use the Zend class for adding an encryption layer, but that will have to wait for a while.
In the process to move everything from POSTs and GETs to sessions for security reasons, a couple things broke in the uploader and am devoting all my available time (which is a little rare due to the full time job I have) to fix it.
Anyways, I'll make sure to get a demo version up and running to get some feedback from those following the uploader
