these types of signals can be assigned different meanings, from day to day depending on briefings.

it is also possible to depict roman numerals with lace patterns, and using under/over eyelet lacing to further increase to combinations or provide a bit of stego in the mix. you can send a shill signal with X's and a real signal with laces through eyelets.

these sorts of things are used popularily and certain affiliations creedos or type of date your looking for in a fetish bar are often communicated by display of accessories.

so its not a big secret anymore its just a matter of getting the context of the signal. so how you lace your shoes has different meaning in a night club than in front of the embassy
