I'm very happy & excited to see people implement services using Arbitrary Transactions.

I agree with the reservations - FTTB it's first come first served approach.

I was just wondering about the following 2 things:

• The first x slots (1 to 9 and 101 to 109) will be used for some more core/central function or they are reserved because of some reason?
• If someone decides to use one of the already defined ports/ would he be able to create problems? If yes, how can we overcome it / could we add one extra form of authentication?

TIA,
