performance enhancement by working copy svn server

Basically, just wondering if anyone has ever thought along these lines ...

I was thinking about how to speed up operations, such as svn status, etc, which are currently required to walk the tree. With large numbers of files, this can be expensive. The root cause is simple - peoples files can be changed by any process without the knowledge of svn; therefore svn must inspect each file to see if it's changed. To improve this would require some process to have the ability to constantly monitor all file access within the working copy.

So the idea is - Suppose there were a special "working copy" svn server, which could have exclusive access to some folder on the system, containing the working copy, and then export those files to localhost, where they could be mounted into a user's home directory (or wherever). The user would work in his/her home directory as always, but the "working copy svn server" would be able to monitor all file access. No change of behavior would be necessary; the working copy could contain versioned and unversioned files exactly as it always has, but the "working copy svn server" could keep track of all the local modifications on the fly, and eliminate the need to ever walk the tree.

Granted, root would have to assist somehow, to let the filesystem mount. And I'm sure it's not a trivial code to write.
