If you want to change the svn:author property you can do this in a
pre-commit hook. Something like this will set the author to "sid" on all
woody's commits:
[[[
#!/usr/bin/python

import sys
import svn.fs
import svn.repos

repo = sys.argv[1]
txn_name = sys.argv[2]

repo = svn.core.svn_path_canonicalize(repo)
fs = svn.repos.svn_repos_fs(svn.repos.svn_repos_open(repo))
txn = svn.fs.svn_fs_open_txn(fs, txn_name)
author = svn.fs.svn_fs_txn_prop(txn, b"svn:author")
if author == b"woody":
   svn.fs.svn_fs_change_txn_prop(txn, b"svn:author", b"sid")
exit(0)
]]]

(The translation table is left as an exercise for the reader)

Cheers,
Daniel
