Mostly because i'm doing a world reset for 1.3.1 (so the temples and such will appear) and plan on firing up the (private*) server again now that logistics pipes has no choice but to be SMP now. That's one of the essential mods I can't play without anymore. Just like IC2 and the q-suit (helmet) here.
So yeah.. don't want to go through a bunch of effort for something that'll be going away in a few weeks.

can't see your point, since you'll have to create the prototype anyway and i doubt you'll do it in your real world since prototyping something like that leaves nice holes
by what i see an ice CASUC should actually be much easier to frame than a bucket CASUC. to frame the "ice farm" is trivial, you don't need to worry about extracting something which saves complexity and ice stacks, which makes it much RP2 tube friendlier than buckets. i don't know about logistic pipes, but RP2 tubes would "refill" your generator on what is missing and send the rest back till some ice is missing again. you could just spam infinite amounts of ice and never lose something since RP2 tubes never drop items. the system would only "jam" if it's to much, but that just means that you have way more ice than the generator can use which stops the ice production completly till it's needed again, which one the other hand is a good thing.
if you would give me the exact machinary specifics for a 5chamber ice CASUC (number of machines, upgrades, ice slots in generator etc.) i'm pretty sure i could construct something like that in a few hours.
