I don't personally use such things, but with the restriction on the interval between fetches, would it be possible to have some sort of "development" version that doesn't hit the db, but still spits out XML in the form that this ticker does? I know that if I were to create a client for this, I'd probably need more than 50 tries before the time restriction kicked in. Moreover, it'd be nice to continue development on such a thing and not have to deal with waiting 10 minutes in between authorized refreshes only to find that you forgot something.
Feel the white light, the light within
Be your own disciple, fan the sparks of will
For all of us waiting, your kingdom will come
