I put together a pair of simple encryption/decrpytion programs that encrypt
the data with a simple pair of keys.  They you send the encrypted data.  Once
everyone has sent the data, you exchange the keys.  I think some standard
packages can do the same.  This isn't foolproof if the person wants to
cheat (such codes can be broken by brute force), but prevents against
accidents and simple temptation.

You could even just uuencode the data (assuming you trust the person and
want to avoid accidentally seeing the data).
