This is true, and it's usually the best way to do things. I thought about
this, though, and came up with an inefficient and kludgy way to transfer stuff
using an interactive ssh session and a couple of evil Perl scripts:

#!/usr/bin/perl -w
# file2hex.pl
$i=0;
while(read(STDIN,$l,1)!=0){
        printf "%02x ",ord($l);
        $i++;
        if($i==15){ print "\n"; $i=0; }
}
# end

#!/usr/bin/perl -w
# hex2file.pl
while($l=<>){
        chomp $l;
        @a=split(/ /,$l);
        foreach $c (@a){ print chr(hex($c)); }
        }
# end

2 konsole tabs/whatever, one on machine1 , one on machine2:

machine1:~$ file2hex.pl < somefile | more
machine2:~$ hex2file.pl > somefile

Copy screenful of hex, paste into other session, hit spacebar, repeat until
done, hit Ctrl-D on machine2 session after last screenful pasted. Net result
is to transfer somefile from machine1 to machine2.

This is really a terrible idea, and if you can transfer the files in any other
way, it's preferable. But it does seem to work.
