And would the Eldar let the Tau become the most technologically adept race in the universe, would they let the Tau surpass them...i don't think so, and to strike while their technology is still more advanced would probably beat the Tau down or at least slow their growth rate significantly.
Just a thought or two...
I think you're hypothesizing based on some false assumptions. To start, the Tau are far more resilient than you give them credit for.
The Tau have already met the Tyranids and were "able to scatter and destroy an entire splinter fleet without the loss of a single vessel" with the leadership of Commander Shadowsun. (Tau codex, pg. 46)
They have also stymied a full crusade of the Imperium and bounced right back in what is known as the Third Phase Expansion.
The Tau are uniquely adapted to life in a galaxy overrun with Chaos. They have no psychic impact at all in the Warp, and that makes them useless and all but invisible to the Warp Gods. If we think along the lines of natural selection, the Tau are destined to outlive every other race that is tormented by the corruption of the Warp.
As for the Eldar, why would they have any reason to hate the Tau? The Tau have found a relatively peaceful lifestyle that maintains balance even in a hostile galaxy. That is exactly what the Craftworlds are striving for with their strict teachings. And the Tau, of course, would typically welcome any Eldar they meet to diplomatic relations with their Water Caste. Unfortunately, the Eldar are far too stuck-up and proud to actually let such talks amount to much. Chances are that the Tau would at least learn something from the Eldar, though.
Sorry, that went a bit OT. I feel that the Tau are about equal with the Eldar in terms of the advancement of traditional technologies. However, augmented with "magic" pysker powers, the Eldar tech is still much more capable. Remember that the Eldar held the power over a even sun before the Fall, and they still hold that level of knowledge in secret.
