This is my view also. There are some intriguing connections between
Indus settlement in Oman and even Bahrein (Dilmun) used Indus Valley
weights and measures, not Mesopotamian ones. If the Indus
civilisation was basically Dravidian this would suggest a close
Dravidian connection to Dilmun, the supposed Sumerian homeland
(according to Sumerians themselves).

I have seen a number of connections with Hurro-Urartian. The Goddess
Innana is non-Sumerian and is related to the Hurrian Hannahannas. I
have seen the Sumerian river names - Tigris and Euphrates are related
to the Hurrian hydronyms, suggesting they arrived in an area where
they already had been named by proto-Euphratean (proto-Hurro-
Urartian?) speakers. There is also evidence that the words related
to copper working and smithcraft were also all Hurrian derived.
