Linux "Additional real-time technology will be incorporated into the mainline Linux kernel starting with version 2.6.18, TimeSys reports. The real-time support, which previously had to be installed as kernel patches, was developed in part by TimeSys senior open source developer Thomas Gleixner, the company says. Gleixner was the main author of Linux's hrtimer (high-resolution timer) subsystem, and has been a major contributor to Ingo Molnar's real-time preemption patch. The changelog for the 2.6.18 kernel reflects the addition of 136 patches authored by Gleixner, along with 143 from Molnar, who works for Red Hat."

Real-time network applications will not work unless you can assign real-time QoS to the communication channel. Most such applications do only require soft realtime anyway as they are fine with some buffers - hard realtime is for devices. It makes development of specific hardware faster, cheaper, more performant, especially outside of the mass consumer market. (You could even solder your own expansion hardware). - The most common advantage for a desktop user might be with the impossibility of buffer underruns in burning CDs or smooth playback of audio even under heavy load of the rest of the computer; play a modern shooter with doing CD backup in a background process.
