The NPL (Netscape Public License; parts of Mozilla still use it) has this feature. Check out part V of the Additional Terms: V. Use of Modifications and Covered Code by Initial Developer. V.1. In General. The obligations of Section 3 apply to Netscape, except to the extent specified in this Amendment, Section V.2 and V.3. V.2. Other Products. Netscape may include Covered Code in products other than the Netscape's Branded Code which are released by Netscape during the two (2) years following the release date of the Original Code, without such additional products becoming subject to the terms of this License, and may license such additional products on different terms from those contained in this License. V.3. Alternative Licensing. Netscape may license the Source Code of Netscape's Branded Code, including Modifications incorporated therein, without such Netscape Branded Code becoming subject to the terms of this License, and may license such Netscape Branded Code on different terms from those contained in this License. (The Section 3 referred to in V.1 is about distribution of modified versions; it also contains the copyleft clauses.) The NPL makes me want to add a "License must not be overly verbose" clause to the DFSG... Richard Braakman
