There is a very fine line. There is what is known as brown bagging or selling or trading at the show without going threw the coast of getting a table/booth. The dealers who did pay for booths and the blade show folks that who did not get paid for a booth get very up set about people brown bagging. So I would doubt any thing formally organized is posable. That being said people meet in the lobby bar "the pit" and in front of the hotel (think tail gate with more booze and no food). When a larger group of like mined people get together there is always some business done, and no body minds. That being said if you are doing enough that people notice (hustling) you will not be well regarded by a large group of people armed with at least several knives each. My advice is if you are looking for one or thing you really QUIETLY work the crowd if there is one thing you want to move work the crowd. Other wise get a table or fined a vender to broker a deal for you.
On a side note if you have not been there is a huge social seen and you will have lots of opportunities to talk, hang out, and net work after hours. There are several makers hosting dinners (they set it up you pay). If you can, get a room at the Galleria because that is the epicenter.
As a disclaimer I am a maker, I do have a both this year, and this will only be my 3rd show (one as a fan, one as an apprentice, and this one as a maker with my own booth). If you get their and need some guidance I have booth (220), stop by, I lived in the area, and will be glad to try and point you in the correct direction
I hope this helps and I hope to see you their
