The scheduling and reordering algorithms are proprietary, however, they are not necessary to MP-DCCP and can be omitted. Is that enough to solve the license concern? Is the scheduling in the kernel? If so yes, it will cause a MP-DCCP not to be accepted. If it is all done in userspace, then it leaves option for someone to reinvent their own open source version.
