looks like its only available for certain types of Creative Commons licensing so at this point I don't think I would be interested. Roy, from what I gather you can order a print and flickr will print and ship it. Just like FAA, although FAA at this point offers more options in terms of paper types as well as framing.
if further expanded, this move by flickr could change the landscape of POD. They were probably aware that people were bypassing them and decided to cut out the middleman.
Sorry if this is in breach of FAA rules; I think the news is relevant enough for our community here to share and maybe discuss as it does have the potential to be big.
