we have to upload and download documents which can easily extend
500mb(requirement). Except for the traffic I'm not really worring about the
download part. The upload part is what i'm uncertain about. Even if I raise
timeout and max document size, i have the feeling this not what sharepoint was
designed for.

So my questions are
- Is it sufficient to raise the timeout and max document size?
- would the windows explorer access / webdav behave differently
- does the active x control (multiple upload) perform better (binary upload)
