First of all I wouldn't be using _ipp._tcp. IPP is the 'Internet  
Printing Protocol' according to http://www.dns-sd.org/ 
ServiceTypes.html. For Bonjour (Zeroconf) chat you are best off using  
_presence._tcp (see above link for way more info than you need).

So basically if you do what you have above and then open up pidgin  
with a Bonjour account type you should be able to see your  
registration appear (of course you won't be able to chat until you  
implement that part of the Bonjour chat protocol - which you can find  
from the references in the above link).
