Can I ask that we steer away from hypotheticals, at least on this list? We're talking about Cygwin and it's licenses. You have a choice of GPL, a compatible open-source license, or the "buy-out" license (see ). Since these license discussions can get tiresome quickly even when they stay on-topic, it's best to keep as focused as possible. The list appreciates your efforts in this regard. -- Larry Hall http://www.rfk.com RFK Partners, Inc.
