The file would be specified as an "smb:" URL.  For example:

    smb://server/share/my folder/my programs/SQLNEt/TNSNAMES.ORA

As a side note, it might be useful to have the SmbFile constructor check
for a leading "\\" in the string argument; if present, convert:




This would provide a more direct "drop-in" replacement (as java.io.File allows
UNC names on Windows).
