I don't think there is much similarity between Theora and VP6, so you
need to do proper transcoding, just like between Theora and H.264.
I don't quite understand the second question: Flash can indeed load
local files, but you couldn't enforce a hook into Flash to transcode
the remote file before loading the local transcode. This functionality
would have to already be included in the SWF that you download from
