What's wrong with xargs? Since scp doesn't allow the --target-directory
(-t) argument of cp, you could do something like
find . ... | xargs -r /bin/sh -c 'scp "$@" target_directory' DUMMY
The above should copy substantially more than one file per connection,
unless you have *really* long filenames. You do need the DUMMY parameter
(or else you'll lose the first filename).

Not that I know of. IIRC, the argument list length limitation doesn't
apply if Cygwin exec mechanisms are used, so if the above isn't good for
you, try mounting the executable (scp?) with the -X option (see the mount
man page for details).
