That's exactly it. We try to share a common base object, but as I was
still experimenting with my own interfaces, I may not have shared as much
as possible. If possible, in the long run, we want to move up methods
from the LineFrontend class to the BaseFrontend class.

Well, not really. I use an ipython1 instance (the Interpreter), but I
also instanciate an ipython0 to prefilter the lines to give the magics
and other goodies. In the long run, we should try and get rid of this
instance as the magics get abstracted from ipython0.

In block-oriented you can edit several blocks at a time. Line-oriented
does not know what blocks are, and only knows how to edit the last line
(or set of lines, in my case). Line-oriented is weaker than
block-oriented. For asynchronuous operation, block-oriented makes much
more sens than line-oriented.

Cheers,
