We had two teams in separate physical locations. We worked together occasionally, but most of the time projects were fully staffed at one location or the other. The Scala change was fully supported at one of the office and not the other.

It wasn't too difficult to convince the CTO that Scala was the right choice. He's a big OSS advocate. From a technological perspective we were trusted to make the right decision.

I think what really sold the the rest of the management team was how much money we could save in licensing fees.
