Yes. OMC will make stable releases from time to time and base our standard commercial offerings on such releases. Those commercial offerings are available under the GPL as well and you can purchase a commercial license to any version of our products.
The reasoning behind regular stable releases are that it would be a maintainers nightmare to provide commercial support to any one release from our source tree, as many of those would be beta or alpha releases.
We will therefore fork the Brutus source tree from time to time and maintain that code fork as a stable "bug-fixes only" release upon which we do standard commercial offerings.
