It may be then, that a quad 3GHz xeon + 4G RAM is a usable server

Should the Terminals be 900+MHz / 128M RAM, It may also be that local
apps is a solution.

The advantage we have with Linux, is that we may manipulate the software
and simply choose one of the above solutions - sometimes based on
convenience, if we can afford it, and sometimes based on price.

I have not seen a lot of discussion here on 'local apps', probably
because many choose the former option, because they can.  Which is very
nice of course.  8-)

K12LTSP should, IMO, always be able to boot a 486DX sh*tbox into a
usable terminal, but the higher-end terminal equipment is becoming more
common, and the expectations of K12LTSP (viz current example) are

discussion trails off.....
