jgit has a vfs abstraction for the different dumb protocols. Not sure if you would find it of any value to read as we are also able to use a number of Java standard abstractions like InputStream/OutputStream, but here it is:

  WalkRemoteObjectDatabase:
  http://repo.or.cz/w/egit.git?a=blob;f=org.spearce.jgit/src/org/spearce/jgit/transport/WalkRemoteObjectDatabase.java;h=915faac9eb85e59c0ed2c08b9631d03cbc4c6bf8;hb=8d085723b260f3b51a70d11b723608779160b090

Thus far this abstraction has worked for sftp:// and amazon-s3://. WebDAV may make it more complicated due to locking being available (and something we would want to use to protect writes) but S3 uses HTTP PUT much like DAV does to upload content so there wouldn't be too many changes to actually implement DAV support.
