Certainly multiple scps would take lots of time due to initiating
multiple ssh sessions.
However, you can transfer multiple files in scp command if they are
going into a direcotry. Then scp turns out faster at 3/4 the time of
sftp!
#### SCP ####
[]: time scp -q devrat:dev/ContextFree/_darcs/patches/*.gz p-scp

Connecting to devrat...
real 0m24.749s
user 0m0.868s
sys 0m1.303s
I ran this several times and these times are representative. (For
the curious, the test data set was 5.8 megabytes in 354 patches from
a real darcs repo.)
Of course, I'm not sure I know the efficacy of doing this, since
command lines are usually limited in length....
