[TYPO3-dev] Workspaces and files support

[Dobes Vandermeer]

I'm looking at the possibility of extending typo3 so that the workspaces  
concept works for files.

Because the designers are entering filenames into their TemplaVoila  
templates, we don't want to make existing files read-only in non-live  
workspaces; we want to actually support multiple versions of each file  
with the same name, so that an image can be updated by a designer without  
changing all the pages that reference it, and their change only takes  
effect when they push to the live workspace.

Unfortunately, I'm not a very experienced typo3 programmer at this point  
(or you'd probably have heard more from me before).  I've figured a few  
things out, but this task seems to require a more broad knowledge of  
typo3, so I thought I'd ask whether any of the members of the developers  
list could give me some pointers, like:

Is this even possible?  What if I only need to support the basic file  
management functions and the references in templavoila pages, but not  
other plugins and features "in general"?

What code should I be looking at?

Thanks!
