I agree with Basjoe, the benefits to the 1,000s of Hummy owners for the modifications (and supporting documentation and guides) is amazing.
I really appreciate that it has been developed in such a way as to be accessible to those with little to no telnet, linux, unix or whatever(!) skills.
It is also clear to me that it has been developed keeping interference with the standard firmware to a minimum - something I applaud.
As a software developer myself (for a configurable off the shelf ERP system) I have seen other 'professional' developers progress with far less regard than af123 does.
Af123's excellent work is backed up Black Hole, brian, Ezra Pound, fenlander, MattC, MartinLiddle, Michael, oijonesey, Sam Widges... and many other excellent and patient contributors.
I think it is time for me to make (as BH elegantly describes it) a concrete expression of appreciation.
