It looks like some sources and mailung list archives for OpenSSI are
still available sourceforage:

	https://sourceforge.net/p/ssic-linux

OpenSSI to various distributions (Fedora, Debian, RHEL), etc., but
they were not focused on getting any of their changes upstream.  The
only evidence I can find of OpenSSI on the Linux Kernel mailing list
was a forwarded announcement of OpenSSI 1.0:

https://lore.kernel.org/all/410DDFA2.40107@hp.com/T/#r2b3cfcce5ccd8127a8493e7987349a1921597537

And apparently OpenSSI had patches to e2fsprogs (since they had a
clusterfied version of ext3), but no one ever sent the OpenSSI
e2fsprogs patches to me for review.  So it appears that it was not a
matter of "the upstream Linux kernel team.... [being] willing to take
the VPROC changes", it was more like no one asked, or prepared patches
that could be considered by usptream.
