) Other than unimplemented pieces of code, there're no known bugs...
  just "features that would be cool." :-)

) On the other hand, this hasn't been thoroughly tested.

) Tag generation is still a little scary - essentially, the library
  ships over a pointer to the callback function.  This *should* always
  work, since the server ought to complete all callbacks before closing
  and because the server should never send us a tag we're not expecting,
  but it's still scary, and should be replaced with something sane
  (especially since even a conservative GC will fail to find any references
  to the callback, since the only reference is on the wire...).

) The whole API approach is rather scary - I can't think of a better way
  to do this, but more documentation is a Requirement.

) Constructors should take acap_Strings instead of cstrings.  This may
  involve some interesting magic, though - possibly a redefinition of
  acap_String (maybe length+ptr, with allocation functions that create
  a string of a given length in a single blob?)  Basically, acap_Strings
  are the way to go, but they're too cumbersome for now...

) We *really* need better error reporting.  comerr would be perfect...

) A better callback interface would be awesome.
