Not Protestant, but the Benedictines, Franciscans, Cistercians, and the like have been doing communal life for a long long time.
Not sure what their current status is but the Amana colonies might be of interest to you.

The Amana Society is well and thriving, albeit without communal living. The Society was converted in the 1930's from a communal enterprise to a regular corporation because the Great Depression had wreaked havoc on the Society. Members were given proportionate shares in the Amana Society. It became widely known later for its Amana brand of appliances which, sadly, are no longer associated with the Society. Also, the woolen mill ceased operation many decades ago, although there is a historical exhibit with an operational loom in the factory. The hand-crafted furniture continues to be made, although its popularity seems to have waned in general with interest in the arts and crafts. Primarily, the main economic engine of the Amana Society is tourism, with tourists being primarily focused at Main Amana, which is semi-authentic. and an Amana commercial development at the Amana exit at Interstate 80, which is not in the least bit religious (or communal).
The Amana Society, as you probably know, has an interesting history as a sort of proto-pentecostal, pietistic spin off from the German Evangelical Lutheran Church. In addition to believe the literal inspiration of the Bible, they believed in the same level of inspiration as being given through their charismatic (note the small c) leaders. Among the beliefs was a very firm preference for celibacy such that virtually all of the true believers had died off by the early twentieth century, leaving the children and grandchildren of the wayward believers who had fallen to the desires of the flesh in marriage.
The other Amanas (six of the seven colonies were named Amana by inspiration) include High Amana, South Amana, East Amana, Middle Amana, West Amana, and Homestead (a village which pre-existed the purchase of the land by the Amana Society) are very small villages without much to interest the casual tourist. Their meetinghouses survive but are not in active use.
The Amana Society is frequently conflated with the Old Order Amish. There is virtually no correlation between the two movements. The Amana Society has never rejected any form of technology for any religious reasons.
