Keep in mind that any application you download and run on your Mac has
the same "unrestricted" access. If Box.net had an application you could
download to work with their service, would you use it? Granting the
Java applet this access is exactly as safe, and as dangerous.

By default Java applications on web sites are very restricted in what
they can do. Their access to your computer is extremely limited, which
means among other things that they can't read or write files on your
hard drive. Giving it this access means it can get to your hard drive,
which is a necessary part of making their drag and drop scheme work.

Whether they deserve the trust this implies is not a question I can
answer for you.
