Is the following sentence perfectly normal/OK?
A system was developed to integrate the internet and cell phones under the SuperSpeed framework by generalizing XCP-IP under the X-Transmission framework.
Does the usage of under sound repetitive here? Would it bother you at all -- if 'under' is appropriate in each case? If it still does, how much (ASSUMING there is another way to rewrite the first part of the sentence to get rid of the first under -- then how much would you be bothered by this suboptimal sentence structure? )?
