For those writing alternative GUI wrappers that target the bitcoin daemon, has anyone had much success in figuring out when the daemon has received new transactions?
So far my solution has been to aggressively poll the daemon. There is a pull request for "push" RPC calls that would notify a HTTP server when a new transaction is received, but this has yet to be merged, and isn't really in a workable state currently.
Does anyone have any other solutions? This seems like the biggest blocker to developing a good alternative GUI (or web service, for that matter).
