Pulse is no longer available under a commercial license. The commercial programme is under sunset until January 2017, at which point Pulse is expected to be open sourced.

If you are a current customer with a valid support contract, you will already have been contacted regarding the commercial sunset. If you have any questions, please contact firstname.lastname@example.org.
Note that commercial customers are entitled to source code access, under a limited license. Contact email@example.com to request a source drop. As above, after the sunset we expect to open source under a more liberal license.
