Not all software is decently written. It isn't particularry hard to write
software that can run on any system regaurdless of byte order, but it
isn't hard to mess up either.

I'm not the greatest fan of it either, but the idea has mert. And you
already said above the problem with ./configure;make (manufactures won't
release source, and don't expect the to help you out either if you try to
attach your scanner to a Sun3 like I've considered)
(as someone else suggested, this is called Jini, someone with connections
should contact sun and see if we can get this part of the standard out
soon. If Twain requires in the next release that all scanners do Jini it
will go a long way towards the goal. [There are competing standards with
Jini, so long as linux and xBsd support is easy to add I'm netural to
which one is used])

depends, the xBSDs have support in stable code, Linux is a bit behind, but
that is promised. Only time will tell if USB lives up to the hype, but I
keep hoping it does, but without the "We won't tell you how out scanner
talks over the parrell port" that we face today.

Hear that Twain team? this is one thing that Sane doesn't have that the
unified standard should.
