  I would rather not be locked to SHA-1.  Can the following work?

   Input      :=  any bitstring
   Hash_Input :=  Context_ID | Hash_Alg_ID | Input
   Hash_Value :=  Hash( Hash_Input )
   ORCHID     :=  Prefix | Encode_n( Hash_Value )

  Where, Hash is the function identified by Hash_Alg_ID, and SHA-1 MUST
  be supported, and other hash functions MAY also be supported.

I do not like the dependence on sha-1 without an upgrade path.  Why
can't the hash function be an input along with the bit string and
context ID?  Each context would be required to choose a hash function.

It seems like 100 bits is far more than is needed for an experiment. If there is some analysis on this is the right size, I am glad to clear.

I did not understand the explanation I got about why a 100 was needed but it does not seem that allocating a /28 causes harm in this case so I have cleared on the basis it causes no harm.
