iPhone Jabber(XMPP) Clients – Missing Features

I have begun researching a potential Jabber(XMPP) client for use on my iPhone. Being a developer and the maintainer of XMPP services at my workplace, I came up with the following feature list that I felt was needed in a potential client.

iPhone Client Feature Requirements:

1. Support for XEP-0133 (Basic server administration control)
2. SRV DNS record resolution support
3. Avatar support (*seems pretty standard)
4. Pub-Sub notifications
5. Push notifications

I have included a table summarizing the results of my findings. I have tried to include as many XMPP clients as possible. Applications like Meebo have been intentionally excluded from the table since they don’t support direct connection to private XMPP servers.
