And sftp does not fit that security paradigm?  It uses ssh as well, so
IMHO should be as safe as scp.

The OP implied he just got his wireless setup, so time to break the wep
key would have been minimal so far.  He also implied this would be a one
time transfer of files.  While I agree with your recommendations for
long term use, a new network, with wep enabled, and set to not broadcast
the essid would be relatively secure.  (I don't know his network
configuration, but sftp would certainly be as secure as scp in the same
environment.)
