Is it possible you are getting too hung up on the technical details?
How about going to one of the ltsp.org lists or looking on their FAQ
"I need to support X number of users with typical home-related uses
(web browsers, word processors, email clients) over a wired network.
How much RAM, drive space, and how much processor speed do I need to
put on the server to support them? How much extra should I budget for
It sounds to me you are trying to second-guess lots of things, and it
might be easier to work backward from "real-world" experiences people
have had actually using LTSP.
Of course, most "real-world" LTSP setups are probably in a classroom
or computer lab setting, so you may run into issues they haven't
anticipated regarding home usage.
Good luck -- sounds like an interesting project!
