Actually it can, and it's also a lot easyer, since there are already made
packages for each of those protocols.

That depends, I think there is a compatibility lib, provided with VC++, at
least, which allows to know the file state information, in a compatible way with
Unix.
The only issue we might have is the handling of the file change date by the OS.
But that can possible solved, with a moke-up of the unix "touch" command, which
I believe already exists for windows.

if we used java, then it wouldn't need to.
Also, why don't we provide a simple text interface, we only want to select
which files, from a list (the ones which are new on the server comparing to
ours) so that the file downloading can proceed.
Don't spend a lot of work on GUIs which won't have any real benefit, at least
for now.
But this is a good point to remind us, that the downloading part of the program
should be self suficient, so that we can later, eventually add a GUI or just a
diferent interface (web interface ? etc...)

Actually, what makes that really easy is the protocol, either FTP or HTTP (using
TCP/IP), open a connection for each file transfer, and all data incoming on that
connection, is considered part of the file; and the connection is closed at the
end of file, signaling it's end.
See ya
