[coyotos-dev] Capability Exchange

[Neal H. Walfield]

How is capability exchange and rights amplification to be done on
Coyotos?  We have discussed, for instance, the mechanism to reparent a
space bank and the mechanism to swap the contents of two objects
(effectively reparenting the object).  Both of these require taking a
capability as an argument and finding the associated object.  I
imagine that the interfaces for these mechanisms might looks something
like this:

  reparent (Bank, Descendent)
  swap (Bank, object1, object2)

Given the capability, how does the server find the object?

Thanks,
Neal
