NEWS says 100 now.

I'm not sure yet.  There may be no single good answer.  The breakpoint
is somewhere less than 100Mbps, but it will as ever vary depending on
circumstances.  If you have a lot of remote machines and very complex
source then it may be that even 100Mbps networks need compression for
optimum speed.

It would be interesting to test fast (55Mbps?) wireless, but I don't
have access to one.

So on the whole until there's more data I'm going to say: >=100Mbps,
use uncompressed; for less use compression.

I considered trying to autodetect it, but I couldn't think of a
reasonable heuristic.  In any case the fact that it needs a server
update made me decide to do it manually and off by default.

I'm just going to add something to the manual.

OK.
