Hey all, subject says it all.

I was transferring some (big) log files to another box on the same
subnet, and while the files were impressively large (5-6gigs each), I
found that the time it would take to transfer them was fairly slow
(more than 12 hours per file).

These were web logs. Nothing secret about them at all. And while I
don't like my *password* being sent across in the clear, I think 90
percent of the bottleneck is encrypting these things for the trip
across.

I didn't see it in the man pages, but I figure I'll ask anyway...is
there any way to do this without majorly rewriting the spec -- possibly
with a modified cipher that drops to nothing after the first X bytes
(effectively shutting off its own encryption?)
