A really interesting discussion here about the legal issues! I am regularily hosting Hoffices and am part of the group steering the Hoffice network and so far I've never heard of any of the problems you mentioned happening... Hoffice is completely based on gift and trust principles. This assumes that people who get invited into your home won't sue you afterwards, if some kind of accident happens. But this is of course not certain and a host might take a certain risk here. In terms of taxation I believe that there is no real threat, as one of the basic premises is that you host without charging money for it. It's a gift to all people participating. In return you get the a group feeling and motivation to work from your guests. Furthermore Hoffice includes a potluck lunch culture, where everybody contributes to a buffet. As home working as such is not taxed, I don't see why homeworking together should be.
