Redpower 2 prerelease 3, Minefactory revisited

Well, Eloraam made it again. I didn't install it yet (I'm currently downloading it), and you can get it at her blog. She also included a compact recipe list in there (or you can go directly to check it here).
I'm mostly interested in the ore dictionary support added to RP2, and how will it affect ore spawning rates (overflowing tin! And copper! Yay! XD). Because, frankly, using Risugami's recipebook was quite a nightmare, considering there are seven possible cuts of any block in the game (cobble, smooth stone, iron blocks, clay, wood...) multiplied for seven or so again (the saw, diamond saw, and the new gem-type saws...). She also added an item detection block, and I suppose I will look into the differences between this and the one in the BetterThanWolves mod (which is more an "entity detector" than an item).

Edit:

Ok, everything went better than expected. No crash, no weird stuff... or at least it looks like it (there was a file I had to put inside minecraft.jar that got me nervous, since I already had another of the same name XD). On the bad news, my recipebook now has 1209 entries (about 800 or so are different applications of saws to blocks...).

So new stuff... The detector block, is like her old redstone pipe for Buildcraft, but only for Redpower2 pipes. New stuff, hidden in the package? Yes, there is. Solar panels, electricity cables (take the red alloy wires, and change the red alloy bars for blue alloy bars), and an electric furnace. Aside from that, three icons I don't have the slightest idea of what are they used for, but by name and position might be related to the red and blue alloy bars in the future (silicon boule, and blue and red silicon wafers).

On a sidenote, my inifinitely supplied BC2 combustion engine seems to be working without any trouble, for more than 90 minutes without any overheating at all.Here you have a video with it:

Now on the Minefactory update... This mod has gone out of hand! No, really! They changed some stuff, and added compatibilities for BC2. And, not happy with that, new machines to convert power between BC2 and IC2!!! It also includes an Oil making machine (it takes 625.000 EU to craft a single bucket, however, so maybe it's better to just convert electricity to pneumatic power...).

Amazingly, however, I regained 3 free item ID's even installing the power converters, the IC2 addon and the mod itself ^^. Now it uses 1 ID per rail and another for the conveyor belt, one for all the basic "machines" and one for the all the power converters, for a total of 8.

Oh, I almost forgot, the IC2 addon allows, among other things, to transform refined iron into steel, which is a little exploit (because 1 steel takes 4 coal and 1 iron bar... it compensates itself, however, with the fact that coal is really needed by IC2 for coal dust, which you use to make the solar panels, artificial diamonds and other stuff).
