Pre-PIE as a PIE substrate?

[Rick Mc Callister]

I saw somewhere, maybe on the web?
(and possibly unreliable)
that Elamite was spoken in SW Iran until the 10th c. AD or so
Is this so?
Are there any traces in the local languages?

>Eg., there are very old Dravidian loans in the Sanskrit of the Rig-Veda, but
>little (IIRC) Elamite influence in Old Persian.

>Although we know from the documentary sources that the whole of southwestern
>Iran, at the least, spoke Elamite well into early Iron Age times and Elamite
>remained as a chancery language into the first century of the Persian Empire;
>_vide_ the inscriptions of Darius I.
