There are numerous user-created chat submissions that have passed through the Portal this year.
I've seen a handful advertised in user sigs, so do a search at the top for chat and see if there's anything you like.
There's also a stickam and something or other chat threads that link to an external site a lot of users tend to congregate on. Try that.
As for the development, implementing things here tends to be a well-thought process. It may come this year, or next, but... one day...
