Yes, the dotLRN source code license has no choice but to be GPL because of viral effect of OpenACS being GPL. However, copyright holder (MIT/Sloan in most cases - we did porting for some modules to Postgres and marked them copyright Symphinity - I would like to make it copyright OpenACS or FSF or whatever the consensus emerges) can release source-code under new license terms including commercial one. So ownership of copyright for source code is important in determining continued spirit and degree of freedom in future.
But '.LRN' logo and the website is a different beast - and its ownership is so far not clear - It is all about ownership of the brand.
BTW, Carl, for how long are you in Cambridge - I am here too. Is a little .LRN / OpenACS social possible? I think OpenACS Cambridge social is overdue... Tali / Dave, you hear ?
