I agree. Commons Net 1.1 final will not be different
from current CVS snapshot version. Only bugfixes are
expexted - no API changes. So we will be able to
switch   to final version without code modification.
In fact, it will make FtpScanner's code easer since
MsFtpFileListParser class that I made as a workaround
for MS Ftp server, will became unnecessary. I can
remove that code later, but I think it will work with
it, too. 
As I can remeber FtpScanner first tries to list files
with default settings of Commons Net (which worked for
most Unix bases systems). If that fails, then it tries
with MsFtpFileListParser. That worked for my case  but
it won't work for other systems. Anyway, new Commons
Net should be more clever - it will recognize type of
server by itself and will use appropriate parser which
are now already implemented (contrary to 1.0 version
where user is expected to implement non-defulat
parsers). 
Listing files with Net 1.1 will always be successfull
and mine MsFtpFileListParser will never be used so the
code should work equally with or without it. 
So David, you can commit Commons Net CVS snapshot
version instead of current version that we use now.

And Bruce, I don't use Windows as Ftp server anymore!
I learned my lesson! ;) But I will try to test it when
I have time...
