Hi Klaus,
Thanks. It's great that you will put out the windows Shared Folders src code.
As for the performance, I didn't do thorough testing, but you can get an idea
by doing this simple test:
share the whole host system drive, usually C:, then run notepad.exe
then launch map the shared drive in windows XP guest inside virtualbox, say,
you map Z: to be pointing to the host c: drive. then launch notepad.exe by
typing z:\windows\system32\notepad.exe
You will note that it's much slower compared to local notepad.
Thanks,
Huihong

To be honest I don't know. I'm not the one who wrote that code.
But I've asked them and learned that this issue is mostly solved. We
need to update a few things (e.g. using the WDK 6001) then we can make
the code part of VBox OSE. So I'm asking for a little patience since
such cleanup work isn't really high priority. I'll let you know when
we're ready.

See above. Hopefully done in about a week or so.

For contributions there's a wiki page describing the process:
http://virtualbox.org/wiki/Contributor_information
Contributions are always welcome if they actually improve things. What
tests did you run on your implementation? Getting a filesystem
bullet-proof is hard work...
