Andy is using 'proxy' in a different sense than a 'proxy server'.   
'proxy' in this sense means a program which stands in for the true  
connection. The setup would be:
iPhone is 'available', whatever that means (Adium Mobile is running,  
for example): Messaging service –> Adium –> iPhone running Adium  
Mobile –> Adium –> Messaging service
iPhone is 'unavailable' (another app is running on the iPhone, or the  
iPhone is out of service range): Messaging  service –> Adium –>  
Apple's server –> iPhone with Adium Mobile installed

–>, each connection, may of course be routed in whatever way works:  
ethernet, wifi, through a proxy server, over EDGE, etc.
