Non-Indic sustrate vocabulary

[Ed Sugrue]

A quick query...  does anyone know whether anyone has ever compiled a database,
or even just a plain old list, of possible NON Indo-European lexical items in
Sanskrit?  My thought was that they could be examined with an eye to their
possible value to efforts to decode the Indus Valley script.  Does anyone know
of anything like what I'm describing?
