Hmmm let's see.
Several mb of rather untidy code, reliying on an alien GUI-set, and functionality not available
in AmigaOS (like the infamous fork()) in exchange for a few thousand $ ?
Yeah, I can see people lining up for that ....... NOT.
My advice:
Check if it really has to be Mozilla, or if a KHMTL based approach wouldn't be better.
Set up a road map, with how it should be achieved, and split it into parts suitable for single
coders with each of them a fixed part of the pot attached to it.
