I've tested both options (just in case), to mount using "ntfs-3g -o ro /dev/dsk/c0t0d0p1 /mnt/usb" and "mount -F ntfs-3g -o ro /dev/dsk/c0t0d0p1 /mnt/usb".

When reading the only difference between ro and rw
is the updating of access times (not done in ro).


In some situations the low level driver ("mount -F lowntfs")
may be faster.

This is a good throughput to an USB key.
On a spinning disk, I get about 20MB/s on Linux, but
I have not much experience on OpenIndiana (and none with
OmniOS).
The bottleneck is generally the fuse communication
between the kernel and file system driver in user space.

As a developer, I only maintain the sources, and just make
available the executables which I am using myself.
It is up to the distributors to do the packaging with their
own tools. I can accept merging into the common source code
some ifdef'ed code specific to a distribution.

ntfs-3g (including ntfsprogs and the fuse library) is maintained
on sourceforge : http://ntfs-3g.git.sourceforge.net/git/gitweb-index.cgi
and the fuse kernel module for OpenIndiana is maintained on
github : https://github.com/jurikm/illumos-fusefs/commits/master/
