Best way to aggregate content for reading offline

I started using Instapaper  a looooooooooo . . . ooooooooong time ago for aggregating things I wanted to read later.  However, less and less of the content I want to read is actually in the feed or article that I have at hand to forward to Instapaper (via my personal Instapaper e-mail address).  So what happens is that I go to my Instapaper feed, sync it to my Nook, for example, so I can read it offline, but when I sit down to read it, all I get are headlines and excerpts; all of the meat of the articles lay elsewhere on some network, so I still need a data connection in order to access it.  Mission failed.

So, it would be great to find a way to not only sync a given feed (or, like my Instapaper, a feed of feeds) with a device or offline app, but to spider that feed and keep all of the content together.

Surely this exists!  Or will I have to write it myself?

Ubuntu + x11vnc + TightVNC = happytime

In searching for the current best way to access remote X sessions, I tried out x11vnc and TightVNC -- not the native client, but the Java app, no less -- and was immensely pleased!  Just ran "x11vnc -display :0" on a remote console, and connected with TightVNC instantly.  No additional config.  The display was very smooth, and resolution was 1280 x 1024.

FYI, that was a password-less session, so if you want to secure it, gotta do a little better than that.  But with a simple SSH tunnel, should only involve another command on the remote shell, right?
