NOTE: This is roughly obsolete, but may be helpful for historical purposes later.  The issue is covered more precisely in [[XEPs]] and [[ClientIssues]] (though no mention of clients that do support {{{jabber:iq:gateway}}} is made - may want to add that eventually).

We need {{{jabber:iq:gateway}}} ([[https://xmpp.org/extensions/xep-0100.html#addressing-iqgateway|XEP-0100#addressing-iqgateway]]) support in the user's XMPP client in order to get the full benefits of [[https://cheogram.com/|Cheogram]].

Is the user likely to have this?  Here's a survey (see also some [[https://gitlab.com/ossguy/sgx-catapult/issues/6|historical details]], summarized below):
* Conversations - [[https://github.com/siacs/Conversations/issues/1601|not supported]]
* Gajim - supported
* Psi - supported
* Movim - supported
