I agree:  I use Thunderbird, and it works well.  But I read NNTP newsgroups on 
several devices, and I would really like to have the read-status synchronized 
across them.

Can anyone recommend a solution that also synchronizes post read status?  If 
Google Reader or something like it handled NNTP, I imagine I'd use it to achieve 
this benefit.
