SCO OpenServer uses STREAMS TCP/IP; SCO UnixWare 2.x uses STREAMS TCP/IP;
SCO UnixWare 7 uses STREAMS TCP/IP; Solaris 2.6 for SPARC (and presumably
Intel) uses STREAMS TCP/IP. I don't have a Solaris 2.7 here, but I doubt
if it is any different.
Just what do you mean by "most of the commercial Unices"? If you go by
counts of units in the field, the ones that I just enumerated are the vast
majority of commercial Unix systems.
Are you saying that TCP/IP on Solaris SPARC is slow? I don't think so.

What we've discussed is an open-source driver sans QSound, but
with all the basic functions (and they're quite good -- SB done
clean from the git-go for PCI, several efficiency hacks, etc.
AFAIK it'll be quite a bit better than the usual run of sound
cards even without QS stuff)
The QS stuff gets bound in as a library call under the library
license model, and since it's just a handful of routines for pure
data massage to be piped though the main driver it should be
totally immune from portability issues.
Personally, I'd rather that the drivers were totally open source
too. With every wannabee game developer on the planet getting
the open kimono it's not like this stuff is REALLY secret, but
VLSI is contractually obligated and that's that.

IIRC the way Digital specified the north bridge chip we did for
them, there is a mapping table for PCI-DRAM. In our chip there
were physical limits that prevented the large memory issue from
coming up, but the DEC gang had thought it out in advance and
had a consistent memory mapping architecture that would take
them well beyond 2**32
IOW the PCI bus was working with sorta-virtual memory.

PCI-64 addresses are still 32-bit. Intel didn't *want* PCI to
last into the 64-bit system era (watch the news about their
current bus wars with the IBM coalition.)

If this is so, then perhaps you can account for the following phenomenon:
On a Solaris 2.6 SPARC, I go to /kernel/drv and do an "nm" on "tcp" and
"ip". I examine the resulting list of external symbols. I find plenty of
references to the STREAMS routines (putnext, allocb, etc). But I find _no_
references to any symbol containing the characters "sock".
I am supposed to believe that there are two parallel implementations of
TCP/IP in Solaris? If so, what is the driver name of the "socket based
TCP/IP"?
My understanding of what actually happened with Solaris is this: There used
to be a user-level library that implemented socket calls in terms of TLI
calls. This was highly ineffecient. So they moved the socket interface
into the kernel but still copy user data into STREAMS messages which get
passed to the STREAMS based TCP/IP stack. What gets bypassed is the extra
API library in user space.
Also, it is my understanding that HP-UX has gone from a BSD style of TCP/IP
to a STREAMS based version. Just the opposite of the "trend" that you and
others have cited.
I claim there is no such "trend". Implementations that started out as
STREAMS based have tended, largely, to stay that way and implementations
that started out BSD style have tended, largely, to stay that way as well.
SGI might be an example of a switch in one direction, but HP is an example
of a switch the other way.

Maybe it helps to check the file /proc/devices. There is one line

RMS says that Guile Scheme will take over from elisp, and there is a
page somewhere (on www.gnu.org? under the guile pages? not sure) which
discusses conversion issues.
So yes, it's likely to happen.

Further, the page cache (the last column of meminfo output) contains all
