Cool, I'll do it. Looking at CVS, I'm glad I didn't get far with the
1.1.0 version. There, it seemed I'd be returning a not implemented
message for pretty much everything but USER, PASS and STOR. Now it seems
I'll be making an IFTPShell that raises exceptions instead. Is this
right? The thing I'm less sure about is how the actual STOR works. I
won't be getting onto it for a few days, in any case.
