options for git on Amazon S3

Here's the options for backing up git on S3 as I see them now:

• jgit - standalone java app that does git fetch and push to S3. I currently use this one, but it doesn't work with transparent proxy apps such as proxychains. Occasionally I use an old laptop with no wifi or bluetooth, and so want to use a USB-tethered Android G1 for internet access.
  
• S3-backed Filesystems
  
  • Jungledisk
    
  • s3fs
    
  • FuzeOverAmazon(also called s3fs)
    
  • s3fs-fuse
    
  
  
• gits3 - a git implementation that can push to s3. Pretty new. Is it stable yet?
  

I'm tempted to try the filesystem options, but I'm concerned about reliability and transparency (I want more visibility into how the S3 ops are going).
