Not sure how I missed this, but in September Opera announced a licensing agreement with Adobe that gives Adobe the rights to incorporate Opera's browser rendering engine in their products.
Macromedia already has a similar license for their Mac products, but Adobe's license covers both Mac and Windows.
My hope is that this will lead to the availability of an embeddable version of Opera that any developer can use. I would love to embed Opera in TopStyle, and perhaps even FeedDemon.
