I want the integration of a desktop rss client in Linux and Google Reader

But there is no client that can fully integrate with Google Reader. I mean not only synchronization of subscriptions, but also commenting, sharing, like and so on.
But you must admit: how convenient it would be to work with rss feeds offline (for example, from a netbook on the road), and then, when connected to the network, synchronize the data.
Yes, I know about Google Gears technology, but that’s not quite right. Gears is designed to work with an unstable connection, and I want a completely offline work with the ability to synchronize.
As far as I know, they plan to synchronize the tapes in Akregator (an rss reader from KDE), but when it will be is unknown.
Has anyone come across something similar?
