<p>XEP-0237 FTW. Needs a new construct, since the subscriptions element in XEP-0060§5.6 will only list the user's local subscriptions (ie, to their PEP nodes). Maybe just the new namespace defaults to everything instead? But we'd still need the XEP-0237 model.</p>

<section2 topic='Auto Subscriptions' anchor='autosub'>
<p>Servers need to subscribe to remote PEP services with a "mask" containing those nodes which are of interest. Interest needs to be detirmined by the client issuing a request; but this implies that servers would gradually acrue any node type which the user has had a capable client at any time.</p>
<p>Servers need to subscribe to remote PEP services explicitly those nodes which are of interest. Interest needs to be detirmined by the client issuing a request; but this implies that servers would gradually acrue any node type which the user has had a capable client at any time.</p>
<p>Perhaps timing out node types which have not been requested for over a certain period?</p>
<p>For legacy remote PEP services, the server needs to inject +notify caps into the presence.</p>
<p>The server also needs to remove +notify caps from legacy clients and spoof traffic?</p>
<p>Probably use this to handle point 2 in Device Agility, too.</p>
<p>TL;DR: Clients explicitly request a set of nodes (but not domains) that are of interest. I'm calling this the "mask".</p>
<p>Clients can use +notify to handle auto-subscriptions between clients and their server.</p>
<p>Servers receiving +notify from accounts known to support this protocol ignore them.</p>
</section2>
<section2 topic='Filtering' anchor='filter'>
<p>Clients filter subscriptions using a specific stanza (iq, probably), containing a list of nodes. This can be used instead of the odler +notify (which is broadcast).</p>
</section2>
<section2 topic='Interaction with MAM' anchor='mam'>
<p>We probably want to say that events are now archived by MAM, but this may imply that clients need to filter out such events (or explicitly include them). Maybe the mask above affects MAM queries?</p>
