Yes, it is possible. You can already use the cpp-netlib client to
download in HTTP 1.0 mode binary data -- there are even tests packaged
in the library to prove it.

The plan is to keep cpp-netlib as it is right now able to handle
binary data (of course transferred in the appropriate network byte
order) as it comes over the wire.

Have you encountered a bug that's not allowing you to download binary
data using the HTTP client?
