If you are in need of KBOOT compatibility and Ethernet support you can also look at
http://www.utasker.com/kinetis.html
where loaders are available for almost all Freescale boards/parts - including Ethernet.
Unlike the KBOOT original sources they can be built with almost any IDE.
I have heard that the next KBOOT version is planned for June 2015 and that USB-MSD may be included (although which parts will be supported is not known - the last release from December 2014 actually reduced the supported parts for some reason).
The uTasker loader can be used with any application (it is often used with MQX applications) but its code actually is shared with the uTasker application framework (that is, all drivers, generic protocols, OS are the same source).
It will be interesting to see whether the next KBOOT release will bring together its sources, but I don't expect this will be the case since they are probably developed by different groups who look to have started with different code bases.
