There are a number of ways you might want to do this, but assuming you're
looking at something like this:
1. Users join a chat, or a groupchat
2. User 1 draws a line:
2.1. User 1's client generates an XML extension describing the line.
** Custom XML extension required, but possible.
2.2. User 1's client wraps the XML extension in a message.
2.3. User 1's client sends the message to User 2's client.
2.4. User 2's client receives the message and unpacks the XML extension.
2.5. User 2's client decodes the XML extension to obtain the line.
** Custom code again...
2.6. User 2's client draws the line.
...then you're fine.
If you're using a standard kind of extension layout, like this...
<value1> ... </value1>
<value2> ... </value2>
... then you can use DefaultPacketExtension and everything should work neatly.
If you want anything more than that, just be aware that Smack isn't quite as
easy to extend as, say, JSO.
