License change request

Hello. I'd like to use this module in a GPLv2 project, however, GPLv2 is incompatible with Apache 2.0 (the license you're using) so I can't do that. Could you please dual-license gevent-websocket under Apache 2.0 and some other GPL-compatible license like MIT? BTW, if you'd like to do that, you'll have to ask people who contributed to this repository.
