How about implementing something like this: http://hotaru.freelinuxhost.com/w/res/4.html
into Wakaba / Kareha or giving the option to?

Hmm. It'd be a bitch to keep the database of boards up to date. It might be easier to just use the full URLs.

I guess as long as that would be on the admin's part it wouldn't be that difficult of a task.

Anyhow, it'd just be a nifty kind of extra candy feature. It came up in a talk with me and Snacks on 4chan's /b/ recently and he said he'd be interested (although he was only refering to a global 4chan >>> link, I think).

Yeah, I doubt I'd implement cross-site linking, especially with no central server like iichan around. Keeping an up to date list of things on 4chan is a lot easier than working with say Wakachan.

As for Wakaba & Kareha, that could be a neat feature as option, yet the admin would have to define everything in a config. That in itself might not make it worth the trouble though.
