Back when I started Edublogs, I was slightly obsessed with branding it as Edublogs, rather than as WordPress.
This was down to competition for customers from WordPress.com, and also that I didn’t want to confuse users who didn’t know what WordPress was (WordPress? But this is Edublogs? Eh?)
So, every time there was a new release of WordPress here’s what had to do:
Go into the code and manually replace all the WP icons with E ones
Manually hack out all mentions of WordPress from the admin area
Manually add in Edublogs branding to replace it
Replace the Favicon with an Edublogs (rather than MU) one
