We are only limited because of teh current thinking and structure.

Its not so different from the RIR model.

MIR's are only to be created within a network (AS if you like) they would
not suballocate to customers only LIR's withing their network (usualy
country specific). Other LIR's not needing a MIR would deal direct with the
NCC. UUNET has 17 LIR's currently the MIR would suballocate to these not to
other ISP's or customers direct.
BTW Nice to hear from you.
