1. Booting thin clients via PXE and Etherboot
2. Local devices using LTSPFS
3. Network transparent multimedia (audio and video)
4. Screen scripts, including XDMCP, ldm/sdm, rdesktop, telnet, shell
5. Booting thin clients with as little as 32mb of system ram
6. Use of LTSP scripts and utilities (getltscfg, et al)
7. Passing of VCI string from the client to the server (in initramfs)
8. Transparent pass-through printing
9. Network swapping (NBD is the current implementation, but other methods may include iSCSI or NFS)
10. Ability to specify location of the LTSP chroot tree (default location: /opt/ltsp)
11. Ability to control options per workstation using "lts.conf".

Future requirements still under consideration:

1. remote shutdown
2. Network authentication
3. Bidrectional communication between client and server
4. LTSP-defined local application framework
5. Support for "diskless PC" mode (entire session is run on the thin client)

Many of the items in the above 2 lists are either being developed now, or are planned for the future. The list isn't cast in stone and we're definately interested in feedback.
