Good thing it's open source then.
They interact with each other because of BEPs. This client is a prototype and if it's successful you'll have a whole new source of peers.
And before PeX was a BEP, before Vuze had a Mainline DHT plugin, it didn't interact with some clients either. Hell, even DHT [1] had to go through the same BEP process. Do you expect all software to start out complete?
