Comparing shoot'emups with fbreader is apples and oranges. Let me put it another way. Would you rewrite fbreader from scratch just to have autoscrolling ?

Sorry, but I think you are wrong. There is at least one vertical scroller shoot'em'up game for the tablets and it scrolls the whole screen just fine.

Whatever the developer does or does not think, FBReader + our hardware == no autoscrolling.

What makes you think that the current hardware prevents auto-scrolling?

Autoscroll can't be implemented cleanly with the current architecture. FBReader's portability is both a blessing and a curse, in this case, it prevents usable autoscrolling (here's a test, turn one full page and watch how long it takes to refresh the screen).
If somebody wanted to work on drop-in replacement renderer for libzlibrary, that might work, but in the end I suspect it'd be a lot easier to implement the UI and functionality niceties that FBReader has on something that's designed to run well (not just run on everything) like liqreader. . . .

Autoscrolling is kinda fun, but it is hardly the must feature depicted above, it seems to me. To use it, you need to develop a new skill: "synchronized thinking".
With synchronized thinking, you can understand a difficult concept at EXACTLY the same speed as an easy one! That's right, "see Spot run" and "e=mc2" can be read with exactly the same speed of thought! Whereas people who mechanically turn pages are admitting that for them, some thoughts take longer than others.
Unfortunately, I haven't mastered synchronized thinking...

Could you elaborate on why the autoscroll feature would require a complete rewrite of fbreader? I would like to hear a technical explanation, if at all possible. Thanks.
I'd ask for any better informed person to say if I'm wrong here, as quite some time has passed since I've looked at fbreader innards.

So you'd have to do a serious rewrite to adapt everything to XV style operations, redo the whole interface, adapt font rendering to YUV, etc, at which point you're closer to a rewrite than a patch and it would be very maemo/linux specific.
But, again, GTK should be enough for some light scrolling. After all, even that goddamn RSS widget scrolls (and has to be disabled to save battery).
Now, Lcuk uses YUV because the current version of XV extension does not let him use other modes. And he uses XV to stay compatible with the desktop that does support /dev/fb0 but does not support NIT-specific hardware blitting.

I was excited about this program reading archive files, zip etc but guess I misunderstood. I've some ebooks that consist of like 100 individual html files (each chapter) .... was thinking I could zip them up and view them as one book but guess not? 
4 books, 2 split by chapter annd 2 as 1 long html file. I tried out this new fbreader cuz browser choked on the large files; ironically I ended up really liking this fbreader but now have to use both.
