Using HSMM networked radio techniques many operators can have separate, individual, IM exchanges keyboard-to-keyboard on the same frequency, at the same time.
This is similar to trunked digital repeaters in which many individuals can have separate DV QSOs on the same frequency pair at the same time. So when you transmit on this 10kHz wide HF channel, from your perspective you are in a clear one-to-one QSO with another Ham, sort of like using PSK without the QRM, except that your message is buffered and then transmitted all at once in very short and fast burst. Thus my anology to IM. However, you are actully transmitting to a HSMM radio access point (AP) along with hundreds of other Hams at the same time and on the same 10 kHz channel. So, for example, if you have a beam, all stations would point to the HF AP instead of at each other. If you are using a non-directional antenna, then you would simply look for an AP in the area of the world you wish to work.
