Questions[prosody](server)

I am configuring a Prosody server for use with mobile clients supporting OMEMO. I've picked Conversations as a reference client since I'm familiar with it. What Prosody modules do I need to install to support it?

I am adding the mod_proxy65 module to a Prosody server so that it is suitable for XMPP clients supporting XEP-0065. This allows file transfers between clients that are each behind a firewall (NAT).

Minimal configuration examples:

Component "proxy.example.com" "proxy65"

or

Component "proxy.example.com" "proxy65"
    proxy65_address = "example.com"
    proxy65_acl = { "example.com" }

The documentation (linked above) suggests that the mod_proxy65 component should point to "a bytestream proxy", but what does this mean, concretely? What is an example of a service I should install at the proxy.example.com endpoint?
