Nice tips!, specially the parking brake one.
Here is one of my own:
You can use a rear wheel quick release bolt, which is much longer, on the front wheel, combined with a pair of U bolts and some nuts and washers and you will be able to mount a front rack on a suspension fork.
***DISCLAIMER:***
This setup has worked for me for over 5000km with at least 2000km of them being of loaded touring. It involves messing with your front wheel setup so it is probably not a very good idea. Im not a mechanic but I think I have an idea of what the extra load is doing to the skewer and decided to take the risk. If you decide to implement it it will be your sole responsibility.
