You absolutely don't have to install the apple Bonjour crap to use this. The only thing that is used for is the automatic .local hostname resolution.

Essentially, the Raspberry Pi has the netatalk package on it which allows it to broadcast it's own .local hostname. This is what makes it possible for a user to simply type "coder.local" into the URL bar in chrome and have the Raspberry Pi's IP address resolved.

So if you leave out the apple bonjour packages, you'll just have to figure out the IP address yourself and use the IP instead of the fancy "coder.local" hostname. There are a number of ways to accomplish this, from scanning your network to just plugging in a HDMI cable and a keyboard to the RPi and doing an "ifconfig".
