I've checked it, it works fine so far. But I'm curious, whether you have
performance figures about speed improvement. IIUC, compression works only
for files with a size greater than tramp-inline-transfer-compress-start-size
(4096 bytes) and less than tramp-copy-size-limit (10240 bytes). I've
copied a text file (8187 bytes) from to my local
machine; the used time was 0.6 sec (w/o compression) and 0.4 sec (with
compression), respectively.

Maybe, you have more impressive numbers.

Btw, it would simplify the work, if you could provide patches towards
tramp.el from the Tramp repository.

Best regards, Michael.
