Very sensible of them. :)

I would recommend using an ssh pipe instead, as it offers in-line
compression (and encryption) on the entire UUCP session without
needing scripts that could introduce reliability problems. I've been
using it on my home system since the start of the year, and for a
mailing-list-heavy feed I'm seeing a throughput increase between 300-400%.

A how-to was recently mentioned on the taylor-uucp mailing list, and
it can now be found at http://www.internatif.org/bortzmeyer/uucp-over-ssh/
