Seems I was wrong. See XEP0030/4.1/Example 12.
The answers comes from 'shakespeare.lit' but announces items at
'people|plays.shakespeare.lit'.
<iq type='result'
from='shakespeare.lit'
to='ro...@montague.net/orchard'
id='items1'>
<query xmlns='http://jabber.org/protocol/disco#items'>
<item jid='people.shakespeare.lit'
name='Directory of Characters'/>
<item jid='plays.shakespeare.lit'
name='Play-Specific Chatrooms'/> ...

Initial discovery can only happen on the 'server node', like
'vysper.org', can't it? Otherwise, the client would have to guess.
So, now rereading some of XEP 30 + 60, the client would need to send a
info request to all nodes *.shakeskpeare.lit, to inspect if any has the
pubsub feature. If the domain itself announces pubsub as a feature,
maybe this will yield problems later, maybe not.
For now, I would go on with making it configurable which entity it
announces pubsub on (vysper.org, ${pubsub_identifier}.vysper.org or
${pubsub_identifi...@vysper.org). Don't know if we need more than one
announcement (for different or same pubsub service).

Not as long as it'd yield an item 'pub...@shakespeare.lit'.
