Yes but you are going to need to learn to write LUA. The best way I can think of doing this would be a series of filters (one for each item) hooked up to RedPower wire which is attached to the computer via bundled wire.
Program is quite simple:
If userInput == 1:
(activate appropriate filter and what ever else you want)
elseif userInput == 2:
and so on and so forth.
Not exactly what I meant. I was talking about it being updated at all, to that I find it very unlikely especially consider how the API is just around the door.
Don't expect there to be tekkit for 1.3 because of the developments for the mod API and the fact that modding is going to be really stuffed because of the integration between SSP and SMP.
