Direct2PC is still available and it does work with all DirecTV DVR's the big problem to the DirecTV everywhere is it's not what they advertise. First Direct2PC only works on your home network. Second "DirecTV Everywhere" only allows a very small subset of content to be delivered to any device not on your home network.
I even talked to some people that just had DirecTV installed and they were all excited about using a portable computer or Tablet/Smartphone to be able to stream any and all content from their service to the remote location using DirecTV Everywhere. I then told them that DirecTV Everywhere does not work like that, only a few channels are allowed to be streamed to a remote device.
If they want to do this they would require a Slingbox, shame on DirecTV for implying that DirecTV Everywhere is the same thing.
