- Yes, I agree with You, but maybe its development stands.
- jetpipe lacks some important feature in contrast with lp_server.
- jetpipe has much higher memory requirements (RSS=2052 kB vs. 256 kB)
than lp_server. Resources on thin client are rather low, and utilize
Python on it isn't (I think) so good as on powerfull desktop.

Author, Patrick Powell, seems be still active at LPRng - You can see
http://www.lprng.com and there is mail address: papowell at lprng.com
Proper homepage for lp_server source is probably at
"Copyright" and "LICENSE" files attached with lp_server sources says:
Use and distribution of this software is covered by the GNU COPYING
license. Please refer to this for terms and conditions.
And attached "COPYING" file is GNU GPL v2.
I can tried contact lp_server author, but unfortunately (as you can see:))
my english is too bad for serious dialogue.

How I can do it, please?
For me, it appears that LTSP development team laid some groundwork for
LTSP 5, and then next active development is at Debian and Ubuntu distros.

OK, thank You, I will try do it.
