While masternodes are certainly a possibility for the BERN future, 'seg wit' for BERN makes little sense. First understand, 'seg wit' is a way Bitcoin is trying to deal with its congested blocks and high fees because of that congestion from full blocks by using reserved 'segregated witness' space. BERN supports up to 10 meg blocks already and is nowhere near full blocks, much less considering trading away functionality because of them.

But masternodes could be a possibility in the not-so-distant future, sure.
