Facebook XMPP chat API - device priority

Question

I've created a Facebook app that uses the chat api using the following structure

Strophe.js <-- --> Punjab <-- --> Facebook XMPP

All works fine. My question is: Can I prevent other clients receiving messages once my app is connected?

to elaborate: if a user starts using my app to communicate he should not receive replies at the normal facebook chat ui.

Can this be done?

I don't believe this is possible. You could test it using Pidgin via its XMPP console.

The developer docs for chat lists supported features & has a section on limitations, which begins:

Facebook Chat should be compatible with every XMPP client, but is not a full XMPP server. It should be thought of as a proxy into the world of Facebook Chat on www.facebook.com. As a result, it has several behaviors that differ slightly from what you would expect from a traditional XMPP service: ...

Because of this you shouldn't expect the in-browser Facebook Chat clients to behave like XMPP-compliant clients.
