Well, never say "never" :-) MAP allows via the a-bits/offset-bits setting the range of "excluded ports" in a domain to be configured. Thus, while not set so as a default, ports <1024 can also be used.
There is naturally the non-address-shared mode of MAP to consider (i.e. when PSID length =0). Here each MAP user has a full IPv4 address and of course also the corresponding full port range.
