So many people use chickenbones' other wireless system already (in and out of tekkit), and it's such an easy addition, that would add a large amount of gameplay value, that I find it a reasonable and worthwhile suggestion. It doesn't even have to involve deciphering the other mod's code. It could just read straight from chickenbones' config file to find out whatever id values he is using on that server for those two blocks.
If it's so easy, why haven't you made the peripheral?
It's not appropriate for a peripheral. This is clearly the sort of thing that could and should be a basic rom program within the main computer block, since the peripheral physical device already exists and there is no reason to add more external junk in CC to make things needlessly complicated.
Things like sensors make sense to have as peripherals, like in real life. Things that would be the equivalent of firmware, like this, don't.
ChickenBones has posted some addons for WR on the page as well. Maybe you should ask him to write a peripheral addon (which would be much easier) and not the CC devs to add base support.
I did ask him. And it's not easier than 4-6 lines of code. Very few things in plugins are as simple as this. An addon, even in the most modular and well organized system, would be a whole extra class at the least.
My suuggestion to him was actually to make it so that redstone pulses into the blocks from the sides (currently used for nothing) could increment or decrement the frequency by one, respectively. Which would be easier than an addon, and isn't specific to computercraft, even. And that would be great, but:
1) Still more complex than doing it on this side of things and
2) It would bring less publicity to ComputerCraft that way
This is the start of a very slippery slope. If this was added people would start making requests for other "Easy" things like Why cant CC change the coordinates in ICBM mod why can CC change a sorters order. Why can CC magically control everything.
The ICBM one, why not? It's pretty safe to say that one is not nearly as popular, but still, seems a reasonable request. The sorter thing, no. That's a whooole different ballpark. coming up with a way to interface to work with some other dude's proprietary, custom GUI and multi-part, sequential inventory is dozens of times more work.
The request in this thread is for a single command to change a single data value (standard value on all blocks, with existing convenient hook in bukkit). I've written a lot of code for plugins that manipulate the world (e.g. VoxelSniper brushes), and this is as simple as (after checking if the mod is installed, also easy), "getBlockAt(blah coordinates left of the computer or whatever CC already uses for modems and redstone etc.).setData(new frequency). That's it. Don't even have to decode the frequency into something meaningful. It is an unencoded, unencrypted, unobfuscated data value, like wool color.
If half a dozen other mods came along and people asked them to be integreated too, so what? If they are equally as simple as changing one ID or data value with one command, then that seems like a GREAT decision for the CC devs. Minutes' worth of work, a guarantee of compatibility and stability (its a core bukkit hook used for everything), and easy, cheap popularity brought to ComputerCraft for being more awesome. I'd love to slide down that slope if I were the creator of this.
