Buffering may help smooth those out across a 100Mbs connection - but it might not be able to mitigate sustained peaks during busy sequences that need higher bitrates.
The question is how many movies actually have a sustained peak higher than 100 Mb/s for a significant amount of time.
From what I've seen, bit rates above 100 Mb/s are typically only for a few minutes per movie with only a few second of so called sustained peak >100. That shouldn't be an issue with a proper buffer and the 30% bandwidth margin.
ISTR that it's a big enough issue on a number of devices that people have had to get GigE USB 3.0 adaptors and use them in USB 2.0 ports (to deliver >200Mbs connectivity) as even with a chunky buffer, some titles have sustained sequences with bitrates too high for 100Mbs connections to cope with (particularly if you are using SMB which has a higher overhead than NFS)
