Hi Steve,

This stirred my thoughts and I whipped up a bash script that uses SVK,
find, shasum and ln to build a filesystem view of the root of an svn
repository that consumes moderate storage:

SVK_DEPOT=""
MAX_REV=12345

CO_DIR=validation
HASH_DIR=hashes

svk co -r1 /$SVK_DEPOT/ $CO_DIR
mkdir -p $HASH_DIR
for (( REV=1 ; REV<=MAX_REV ; ++REV )) do
  svk up -r$REV $CO_DIR
  # Hashify working copy
  find $CO_DIR -type d -cmin -5 -prune -o \
    -type f -links 1 -exec shasum '{}' + | (
    while read HASH FILE ; do
      [ -x "$FILE" ] && HASH="$HASH"x
      ln "$FILE" $HASH_DIR/$HASH 2>/dev/null || \
        ln -f $HASH_DIR/$HASH "$FILE"
    done
  )
done

Important assumptions are that each update will take less
than 5 minutes and that SVK uses writes to a temporary file
and then renames to perform a modification.
I've used this to build a simple validation script for my project.
I estimate it will use about 20GB to represent my 1GB repo
and that it will take about 3 hours.
