FUSE fs for git.

Hi,

I'm working on a network fs mount service for Linux (I call it Open Secure Network Services, short OSNS) which mounts sftp access on hosts found in the network (using Avahi) and provides a browseable map to the user like:

sbon@ws-001 OSNS]$ ls -al /run/network/sbon/fs/Open\ Secure\ Network/bononline.nl/alarm/public total 3 drwxrwx--- 5 nobody users 4096 Feb 21 05:05 . drwxr-xr-x 5 root root 4096 Feb 21 05:04 .. -rw-r--r-- 1 sbon users 0 Aug 15 2018 1234 drwxr-xr-x 2 nobody users 4096 Jan 24 04:52 backup -rw-r--r-- 1 nobody users 21 Feb 21 2017 .bash_logout -rw-r--r-- 1 nobody users 57 Feb 21 2017 .bash_profile -rw-r--r-- 1 nobody users 141 Feb 21 2017 .bashrc drwxr-xr-x 2 nobody users 4096 May 27 2017 Projects -rw-r--r-- 1 nobody users 4 Jul 1 2017 test -rw-r--r-- 1 sbon users 24 Aug 6 2017 test1 -rw-r--r-- 1 sbon users 4 Aug 10 2017 test2 -rw------- 1 sbon users 0 Aug 15 2018 'Text File' -rw------- 1 sbon users 0 Aug 15 2018 'Text File (1)' -rw------- 1 sbon users 0 Aug 15 2018 'Text File (2)'

See: https://github.com/stefbon/OSNS

It supports SFTP (over SSH) versions 3 (used by Openssh) to 6 (latest draft).
Other things I want to add is:
- own sftp client (osns_sftp_subsystem)
- backup on server of user defined directories and files (osns_backup_subsystem)
- next to SFTP also support SMB using libsmb2 by R. Sahlberg for
integration in Windows Networks
- fsnotify support in SFTP and in userland using a specific user agent
like osns_client_user (maybe also in SMB) (support in SFTP means an
extension)
- textchat and/or videochat (osns_chat_subsystem)
- forward connection to server over SSH using a simple api to talk to
osns_client for databases, and something like nx (emulation of
desktop)
- an own server osns_server
- support for use in large environments and roaming users (-> CA, ldap etc)

Now I'm looking it's possible and usefull to add a git fuse fs. The thing I ask is:

- is there an api I can use (lowlevel and/or highlevel or whatever is
available)?

- is it usefull, in other words is there a serious benefit of a git
filesystem: does it add something?

Any other suggestion is appreciated,
