Dennis is correct in that there are significant areas where 32-bit
systems will remain the norm for some time to come. And choosing a
32-bit system in these areas is completely correct.
That said, I think the issue is that (unlike Linux), Solaris is NOT a
super-duper-plays-in-all-possible-spaces OS. It's a specialized OS,
intended for specific market segments. Embedded is not really one of
them; nor are ultra-low-end netbooks or appliances such as set-top boxes
(though, with the increasing functionality of DVRs, that may change soon).
Because of that, I don't think it's appropriate for ZFS/Solaris folks to
stray too far from their target audience, given the limited resources.
Now, should someone else outside Sun pick up more development, then
Solaris may move into different markets than it is now.
Solaris/ZFS really is intended for a 64-bit machine which is not RAM or
CPU constrained. And, frankly, making it work on things such as
removable USB thumb drives, legacy 32-bit systems, or with
consumer-grade widgets is (in my opinion) pure sugar-coating to the
central goal of a solid, high-performance, flexible, enterprise-class OS
and filesystem (which, hopefully, will someday include being a true
cluster filesystem :-)
Note that I don't speak for Sun on this, it's just my personal reading
of the tea leaves.

so, we have a 128bit fs, but only support for 1tb on 32bit?
i`d call that a bug, isn`t it ? is there a bugid for this? ;)
I'd say the bug in this instance is using a 32-bit platform in 2009! :-)
Rich, a lot of embedded industrial solutions are 32-bit and very up to
date in terms of features.
Thus :
$ uname -a
SunOS aequitas 5.11 snv_115 i86pc i386 i86pc
$ isainfo -v
32-bit i386 applications
ahf sse2 sse fxsr mmx cmov sep cx8 tsc fpu
$ isalist -v
i486 i386 i86
$ psrinfo -pv
The physical processor has 1 virtual processor (0)
x86 (CentaurHauls 6A9 family 6 model 10 step 9 clock 1200 MHz)
VIA Esther processor 1200MHz
Also, some of the very very small little PC units out there, those things
called eePC ( or whatever ) are probably 32-bit only.
