Between instances of twtxt.net I actually plan to do this. I'm working on more "federation" features that allow users to be spread out over multiple twtxt.net instances.

Of course this doesn't for folks in the twtxt community that just host a twtxt.txt file, but that's okay.

Well, what I was suggesting was a way that you can do this even if you are not using the twtxt.net software; after writing to your twtxt.txt file you could use curl to notify a twtxt.net instance or any other server that implements this same protocol for notification. (The reason being so that registries that collect everyone's messages together need not keep checking for new messages. Of course, this would be fully optional, as not everyone is going to use the notification protocol.)
