Cool. Btw, I had a thought:
If debuggability is a big issue for you right now (i.e., you want to
see plaintexts flying by on the wire, so you can tell things are
working right), then it would be pretty easy for us to make the binary
differ have a special "debug mode". Under debug mode, a delta between
SOURCE and TARGET
would totally ignore SOURCE :-). It would just generate windows
containing sequential blocks of TARGET's text, and ops to insert the
data. (It would also not use previous bits of TARGET -- just send a
series of data blocks, as dumb as possible.)
Just a thought; I haven't investigated implementation, but I can't
imagine it would be that hard.
