 Echolink starts muddying the water a bit.
   * When someone uses their phone to connect to an Echolink node via the internet, which then connects to a repeater via RF, half of the conversation is via RF and the other half is over the internet.
-  * But when two people use their phones to send each other text messages or have a phone-to-phone conversation, then Echolink acts just like any other internet chat app.

 IRLP is a bit similar to Echolink but with more RF:
   * When used to connect two (or more) repeaters together, most of the heavy work is via RF.
-  * But if someone has their own IRLP node at home and use it to connect to other repeaters, then it's a short step away from having an IRLP app on a phone that connects directly to the other repeater and do away with one of the radios.

-Finally, DMR can fall almost everywhere on this continuum.
+DMR can fall almost everywhere on this continuum.
   * When used in simplex or via a stand-alone (or RF connected) repeater, there's little difference with FM (other than it needs to be registered using the internet, which could push it a bit to the right).
   * When repeaters are linked together (via the internet), then it's close to IRLP.
