I don't expect anything is what I'm saying. My money is on that project not getting very far for exactly that reason. FC wont want to change any of his code and Spacetoad will have a real hard time. Maybe not though. We'll see.
Also no way man. Have you seen the SMP bukkit version of Technic? It's awesome. You can have as many blocks as you'd like. We've got mods upon mods on our server. Luxury minecrafting right there.
Actually FlowerChild does most of the programming in BtB. And his code works to this extend that for what is mod is cabable of it delivers good performance. And actually dropping forge made BtW even more popular. The problem BtW had with forge it that everyone played it with a lot of other mods. BtW has filters that work with flowing water... well why not use cheap BC-pipes. So basically all BtW did was creating challange and some kind of progress.
Technic virtually stuffs all shit into on big pack without caring if this mods play well without each other. If there is a popular mod they grab it, just for their own popularity. This might work for IC2 or Redpower but not for EqEx (well... don't get the technic thing within either) or BtW. EqEx literally get's destroyed by the need to balance it against the other mods, so basically it was fun to use with buildcraft, but it destroyes every progression IC2 or BtW has. And now instead of improve EqEx there are several updates just to balance it.
Technic mainly destroyes the decision about what mods you should combine with each other and this combined with an audience that isn't that bright overall created a large amount of people demanding quite stupid things from the modders (or filling there forums/threads with error-reports), because sometimes they don't even know what kind of features belongs to which mod.
So FC was confronted with stupid people blaming him for creating useless stuff or that his mod sucks, because Mod XYZ is better for whatever. And of course the easiest solution was to drop forge, which worked better than he had expected.
PS: Basically his code shouldn't be modified by anyone else, but only by himself... so it doesn't matter how it looks, but it works quite good.
