try "greyspace's" (with quotes)
and you don't have to set an essid anyways, bssid is enough for this situation.
And for sniffers protection, assuming you use wireless, the only way is encryption.
a wpa passphrase with 20 characters that dont make sense is almost impossible to crack.
you can use something smart, for example 1234567890abcd"your small-length-password here"
so you dont have to remember a 20 chars password.
