i know he is one here for sure - because he is me =)
i realize that the end goal is to not need a client at all, but this
lets me try out notify.io right now (just like the sample python
script does for Growl/Mac users).
when the API is stable and documented, it would be pretty easy to add
support to GfW. it already supports the concept of 'subscribing' to
notifications, so these would just be another source to subscribe to.
