I believe Maria is referring to the "companions" community at New Skete where husbands and wives live monastically but married. I do not know the specifics of this community but I do not think there is a precedent for it in Orthodox tradition. Generally, when husbands and wives mutually decide to live as monastics they either do so with the blessing of their spiritual father in their own homes, living as "brother and sister", or they agree to join separate monasteries.
Now, for those who have families or otherwise are not in a position to "leave the world", the best precedent for such communities are the small towns, villages, and residents that tend to spring up around monasteries as around a life-giving spring. You can see remnants of such ancient examples of this in the monastic city that developed around the Glendalough monastery in Ireland, where St. Kevin's cave is found. Today we see people moving close to St. Anthony's Monastery in Arizona, the Hermitage of the Holy Cross in WV, and other monasteries in America and throughout the world. When people live in close proximity to such places, they greatly benefit from exposure to the communal life of the monastics and are united by a common spiritual father and spiritual struggle.
