Does JXTA create hybrid P2P applications?

Hi,

I was wondering if JXTA would be classed as a hybrid P2P platform, where 
peers host their own resources and communicate without centralized 
servers, using servers only to initiate communication,  or a Pure P2P 
platform where in the network is completely de-centralized. I ask this 
as even though JXTA does not rely on centralized servers as such, it 
does rely in most cases on hardcoded rendevous peers during 
bootstrapping to learn of other rendezvous peer, so beyond bootstrapping 
they are no longer used. Does this make JXTA a hybrid P2P platform?
Thanks in advance.
