Can we get Instapaper support?

Although, really, what I want is a way that Safari's Reading List can be auto-flushed to Instapaper as part of my Bookmacster workflow. This could be manual or semi-automatic -- I read articles, use the reading list feature, and then next time I run Bookmacster (or the next time the agent detects I'm online) the contents of the Reading List are posted to my Instapaper account and removed from my local store.
