It's an improved GUI for the PS3 NET Server (the PC side of multiMAN and webMAN).
(hosts are hidden in system tray, remember last used folders, supports up to 10 hosts, white list, etc.)

New in v1.3:
Added option to auto-mount a shared sub-folder (right-click and select Auto Mount on Start).

New in v1.2:
Added option to browse the shared folders and mount them using webMAN integration.

New in v1.1:
Added webMAN options to the popup menu when you click on the PS3 logo.

V1.3
A new the option to auto-mount a shared sub-folder (requested by @datalogger ). To enable it right-click on the folder icon and select Auto Mount on Start. If you need to disable the auto-mount, you can right-click again and uncheck the selected folder or right-click on the Start/Stop button and uncheck the "Enable Auto Mount" option.

The selected folder will be auto-mounted via webMAN every time the server is started.

ADVICE: Avoid to start the ps3 net server *with the auto-mount option enabled* while you're playing a game... webMAN will unmount your current game and mount the selected folder, causing issues in your game

Unofficial Additions: (by tpryor)

- FIXED (v2): Cobra patches works on both Debug & Retail XMB.
- NEW FEATURE (v1): - COBRA 7 Ported

- Faster list of games and movies stored on ntfs devices (almost instant vs. +10 seconds in earlier versions)
- Better support for direct play of movies stored on ntfs/ext (now all audio/video can be played directly, instead of only *mount* MKV or ISO as dev_bdvd)
- New filter by name (e.g list only all games or movies that start with 'M')
- Create ISO from File Manager
- Faster creation of ISOs (removed some unnecessary code)
- Added new ftp SITE COPY/PASTE to the FTP Server protocol
- Improved Hex Editor (e.g. select bytes to copy with [ ])
- And other things that I may have forgotten
