Hi again Jon

What we are using today is an "Early Release" license that's sort of like a beta license. When RTC is made generally available, the license for the GA version (e.g. 1.0) will be a standard IBM license - either a limited-time evaluation license if you are just evaluating it or a warranted commercial license if you have paid for the product. As you've already read, Express-C will be available at no cost.

You asked specifically about EPL or CPL and as you'll see in other thread in which I replied, none of the licenses I described above are open source licenses.

Although 1.0 will be made available as I described above, ongoing development (e.g. for the incubators and the development stream for the next versions, the maintenance streams, etc.) will continue to use the Early Release license.
