Multi-User clipboard

Is this possible?

I asked about this before but got no replies - maybe I worded it badly!

I don't really want to know how to do it, but just if it is possible, before I go on search for someone to implement it.

This is what I want.

1. A user registers (that I can handle)
2. Has access to a sort of online scrapbook/clipboard with several predefined (by me)categories/folders
3. While browsing a site can, when they see an item of interest, click a link/button which adds it to their clipboard in the appropriate category.
4. The information is retained on their clipboard and they can log-in and view it any time.

Basically it is a way for them to extract just the stuff that interests them from a large mass of information and retain it all in one place.

The stuff they add will be text essentially - ideally it would add any text or images between two hidden tags or delimiters of some kind, retaining the formatting. Sort of Snippets.

Unfortunately the site into which this needs to be integrated has hundreds of such items but they are not in a database, which I imagine makes it more complex.

Is this possible? Relatively easy or horribly complex? Anyone know of anything already in existance that does something even vaguely similar?

abbeyvet i think that problem is not that really php involved and maybe it's already solved. in the snippets database you just store the text the user submitted via a form. the form is filled by javascript based on the selection the user did. the selection can be an extracted html snippet, that is done by javascript, too. so where is the problem?

if you need a good library to extract a html snippet out of a html page, checkout the snippet extension for firefox, there should be the whole code available. this is mainly javascript so you can even implement it for your snippet library.
