This is an ancient problem, really.  In my years of dealing with Macintosh
files from the first days of XMODEM/YMODEM/ZMODEM with "Red Ryder" and other
telecomm utilities, this dual-fork/type-creator issue has been onerous. 
There are alot of misconceptions too about how/when/where it's required. 
Most Macintosh data files are actually single-forked.

If file creator/typing information is all that's really desired (few if any
Macintosh *DATA* files carry meaningful payloads inside of the resource
forks), then you can adjust your Control Panels:Internet filemapping
preferences to save downloaded files with various .XXX extensions as a
specified type/creator.

The only "solution" if you want true type/creator embedding with resource
fork recombination is to have the users Stuff (or BinHex) the files prior to
uploading them.

There are some simple tricks a person could use to provide an on-the-fly
recombination of the appledouble stuff into a download that would be
properly decoded by any Macintosh web-browser which supports in-line
MacBinary decoding (most do), but this action would have to be done in a
per-user configuration as the presented datastream would break all
non-Macintosh-browser attempts to download the data.  

If I weren't so overtasked with work that pays my bills, I could probably
whip this up pretty fast.  <RISKY COMMERCIALISM PLUG> If this is worth $$$
to you, feel free to make me an offer. </RISKY COMMERCIALISM PLUG>  

It's up to you as to whether or not you wish to contribute the end product
of this into the source tree for the public-at-large.
