Quotium Technologies
More info can be found at Quotium.com.
Quotium's QuotiumPro product was originally based on the OpenSTA code base.
QuotiumPro is to be retired after its 3.x release and replaced by QTest 4.0 - it is unknown how this relates to the code of QuotiumPro or OpenSTA.
ToDo: Hopefully the guys from Quotium can add more info here ...
