That's good news, and a nice page! I browsed through it, and even without drinking so much coffee :) I have a question: What kind of kernel does the RasPi load here? You wrote there is actually no need for an i386 kernel, but is there yet another one? Another question is RAM. You say, 128 MB is enough. I have a group of PIII (Dell Optiplex something...) terminals here with 128 MB, and it's not enough. They get into LDM, then crash. With 256 MB, they run ok (though rather slowly). Any idea?

Re: [Ltsp-discuss] New Rpi or Odroic C1 for LTSP?
I'm not entirely sure how BerryTerminal works, but since ARM cannot execute x86 code (i386 build of LTSP), I'd guess that it uses LDM and some kind of RDP mixture. You can build a AMD64 kernel, but I find this pointless, as i386 is compatible with all clients, as in extreme cases we have a couple of super old 32 bit machines kicking about. What window manager do you use? As the X server runs on the local client, a heavier desktop will probably leave the system without any memory, good examples of heavy desktops are Unity and the like, along with Gnome3.

Last I looked, BerryTerminal was just a build of various LTSP software such as LDM, ltspfs, etc. and a core operating system that emulates an LTSP thin client. With a thin client, most of the code that the user interacts with is running on the server, and merely displayed to the thin client. This is no different weather the client is running i386 code and the server is running amd64 code, or if the client is running ARM code and the server is i386. live well, vagrant signature.asc Description: PGP signature -- Dive into the World of Parallel Programming.

You should be able to install berryterminal on your clients, or genuine LTSP for ARM without installing any i386 LTSP chroots on your server. Arguably the rpi2 and odroid c1 would actually make decent fat clients... live well, vagrant signature.asc Description: PGP signature -- Dive into the World of Parallel Programming.

Re: [Ltsp-discuss] New Rpi or Odroic C1 for LTSP?
We use the original pi's and berry term with ltsp and then each person uses xfreerdp to remote windows server 2008r2 desktops as windows pc's the ltsp is locked and so the people do not even see it, but it works for 50 plus people in our teams of staff I believe the new pi's may not give too much of a speed increase when using berry term but not sure about using them as pxe boot devices because of the CPU support.
