I've been in need of something as awesome and polished as roundcube but for interfacing with NNTP instead of IMAP/SMTP.

Can anyone hazard a guess as to how hard would it be to replace the back end functions to make them talk NNTP and remove the functionality inappropriate to NNTP (e.g. if news groups are folders, creating/deleting folders isn't a feature that would be useful).

Anyone got any thoughts on this? Or perhaps a link to something that already does this reasonably well?
