i think this is a good point. reading from the frame buffer can
be deathly slow on a lot of modern video cards.
Very true, the only exception to this I know of is some of the modern
Dual PCIExpress cards which use a bus in each direction.

That's what bns does on Plan B.
AFAIK, there's no way on Plan 9 to automate mounts making
everythiing work after the FS goes away.

do you have a reference for dual pciexpress? as far as i know,
pcie/agp/pci cards only have a single bus that goes both ways.
my limited understanding was that

well, sure. i wasn't saying that they are the same.

Maybe I missunderstood.
I mean that unless the server is reached in exaclty the same way
(which, in general, if you want something like automount, it does not)
aan is not enough.
It's fine to reach the same FS on the same address when the net goes
and come, but otherwise it is not IIRC.
On Mon,
Intel integrated and derivatives have an actual "frame buffer", in that you set a base pointer to a contiguous block of memory visible to the adapter and scan-out happens from there. I think the real performance issue for hardware where the frame buffer is in the PCIe shared memory apperture is

Since adding to the name space requires no special privileges,
ordinary users can mount the servers they want to use directly,

Hi,
That is very cool I am doing something similar ( I think ).
In hugs (haskell interpreter) there are some things that relies on

for some of those things.
Now I can use

The server does not get beyond the read() call -- as if the

Hi,
Ever heard of Inferno? Or are you using java purely for the

Actually, I like Java (the language, NOT the fat J2EE crap),
and a trimmed-down Java is also suited for small devices, eg.

Won't srvfs (see exportfs(4)) do what you want (packaging up a

Russ, could, you please be a tad more specific as to what ill
exactly are you referring to?
I was referring to needing special privilege to mount something.
While I agree that Plan9 completely removes the need for
automounter to be a privileged application, I still don't
