I can't speak on implementing uefi support, but I can say a bit about 
implementing a second or third boot loader.

In the main code there are two things that I want to separate to make 
the code more flexible for different boot loaders
1. get_kernel_parameters (merged into master, today)
2. interactive_bootloader_menu

lib/core/lib-ui-interactive.sh - This is the file that contains the boot 
loader code and will be the primary file that you'll want to edit
lib/core/lib-blockdevices-filesystems.sh - You shouldn't have to add 
much here. I have added functions here that are mainly important to 
Syslinux (is_part_active, set_part_active, device_is_gpt, etc...)

Feel free to ask me any questions and look at the Syslinux branch on my 
github page (https://github.com/pyther/aif). I plan on creating a new 
branch in the near future and merging my changes there, since it would 
be too much work to try to backport the latest patches from master.
