So I can assume that all providers would either allow names "/like/this/one.jpg" or change such names on my behalf to whatever delimiters are supported? Or is there a way to get a provider's suggested delimiters for "directory emulation" (like the forward slash in the above example) and "file extension emulation" (like the period in the above example)?

Blobstores generally do not support directories; instead they emulate them using prefixes and delimiters. Previously jclouds emulated directory support to accommodate corner-case providers such as Atmos and the filesystem, while most providers used these prefixes and delimiters natively. One of our contributers did a bunch of work to realign jclouds with the blobstore reality. What does this mean practically? Likely very litter -- you can continue to create /blobs/like/this but need not call createDirectory. getBlob remains the same but in list() you should use prefix and delimiter to limit queries to only the blobs you have interest in.
