jb / thanks for the distinction, but I am
aware that the name of the global automaker was not released in the well publicized news release of Jan 5,2010 which detailed the $5.7mm transaction. However, Steve Dice appears to know first or second hand that it is GM. This also dovetails well with rumours that were afloat around a year ago about GM wanting to sign a contract.
In any case, I don't think the "who" matters much, it's all about the "what" of the contract.
I find it curious, and probably you do too, that some others who purport to know all about Wave and it's relative competitive stance, say they know nothing of this contract at all...
