So my idea: Amalgamate all interwiki-bots (in the same programming-language of corse) into 1 multi-maintainer-project. The advantages would be, that we would use lesser resources, the bot-maintainer could work together, they could use a database together, it would be easier for wikimedia-project-user to contact us (in jira for example or with a mailinglist), if something is wrong, it would be easier to contact the bot-software-maintainer and so on.
Any thoughts about that? Good idea or a "you had too much hot water in the shower"-idea?
This has already happened for the main namespace on Wiktionary, see http://en.wiktionary.org/wiki/User:Interwicket. Obviously it's easier for that bot because wiktionary interwiki links are always between identical titles.
I think it is very sensible to have "the toolserver" be responsible for all interwiki linking on projects (including other namespaces on wiktionary). Doing so would allow a shared database of "correct" links to be built, particularly for articles that are known to be problematic (hey, there could even be a web interface for reporting errors).
Whether the toolserver should be responsible for making "all" interwiki edits is more debatable, but it would certainly be useful to create a more central place for this to happen.
