Benedictines are indeed not all the same; Tyburn and the other relatively new congregations do indeed live under a "one big connected family" system, where people may be moved from one location to another. Tyburn is by no means the only such here; contemplative-wise, the Benedictines of Perpetual Adoration of the Most Holy Sacrament spring to mind, and on the active side of things, I can think of two such examples - the Grace and Compassion Benedictines active particularly in the UK and India, and the Tutzing Missionaries active just about everywhere.
Characteristically, however, all Benedictine houses are completely autonomous from one another, although for various administrative and Canon Law reasons they are gathered into different congregations (a rather different use of the word to that which most people understand). This is a direct result of the vow of
stabilitas: a monk does not enter "the Benedictines", he enters "the Benedictines of $place_name". The House where he enters is his House, and no matter where he might be sent, e.g. for study or a parish placement (in the case of ordained monks) that House is where he belongs.
The emergence and growth of the Cistercians and Trappists modified this somewhat, as a measure against the percieved laxity into which most Benedictine houses had fallen into at the time. The autonomy is preserved, but the bond between a house and its "daughter" was stronger, with the abbot of the "mother" house making an annual visit - and in those times, with travelling being what it was, it could mean a very busy life for an abbot.
So the plans of the DSSME as we've heard about them here are indeed quite Benedictine in the sense that each house has its own superior (although there is no mention in the Rule about the size - the constitutions of individual congregations might have something to say about it though). As for preserving orthodoxy and "good practice" - well, some Benedictines seem to have been better at that than others (history has perfect vision, remember), but if that's what the DSMME ladies are called to do in organising their work, that's what they've got to do.
