Re: How to look at Open Source
Last place I worked at we had code escrow agreements in place with our software suppliers. If they went belly-up we'd get a copy of the source code. We paid a third party to hold it.
When our company got sold off I was assigned to sort through our escrow agreements to determine which would come with us, which would stay with the parent company, and which could be terminated. Many of the escrow arrangements had not received a deposit of code... luckily for us.
