RTOS = Real Time Operating System
For more info check http://en.wikipedia.org/wiki/Real-Time_Operating_System
An RTOS provides among other things multitasking support. It is an advanced software feature rarely used in PIC processors because of the extra program space and processing power it requires (easier to apply multiple PICs to get the same result or use a more advanced processor).

You may try looking at:

1. www.freertos.org for PIC18 series RTOS. It's a free RTOS!
2. www.micrium.com for PIC18 as well. Both of them use C18 complier.

For PIC16 RTOS, http://www.pumpkininc.com/ is a nice place to visit. A lot of information and tutorials in there, too.

And ofcourse there is the free RTOS included with the CCS compiler versions after Nov-2005 (v3.238 ??). For more information check the manual for the #use RTOS and see the examples directory.
I'm not sure on the official status of the CCS RTOS, it is not mentioned in the release notes so might still be in Beta?
