Barbin said that Borland had already been approached by three firms regarding the IDE sale. He added that Borland expects a few more within the next six weeks, mainly from venture buyout groups and the more strategic independent software vendors. “It’s likely to be a combination of the two that would be interested [in a purchase],” he said.
This seems to indicate that the interest is not from some huge monolith like Microsoft, Google, IBM, Oracle, or Sun. But rather from “venture buyout” groups. That's an interesting term... and a little “googling” revealed some little bits of information surrounding that term.
