Image Watermarking / Time-based access

Question asked by jett on Jul 25, 2008
We are trying to implement Alfresco in one of our clients and need some direction on how to address the following features they need:

1. Time-bound granting of access to spaces
Currently, one can invite a user to a space. Is there a way to restrict access to a certain time frame? (e.g. give a user access to a space for a month only).

2. Automatic watermarking of images when viewed
We would like to extend the system so that when a user clicks on a file which has an image mime type to call some library to manipulate the image and add a watermark so that what the user sees after downloading the file is a watermarked image.

Would appreciate any inputs from anyone who has done some similar customizations
