Author of sst extant?

[David N. Blank]

Does anyone know where I might find the author of the sampled sound
utility package, sst, nowadays?  He's listed as:

>     Jef Poskanzer
>     jef at well.sf.ca.us
>     {ucbvax, lll-crg, sun!pacbell, apple, hplabs}!well!jef

in the README, but this address has been a black hole.  I am attempting to
find out if he has updated the package to be 4.1 compatible (or if it has
been done for him by somebody).  Thanks muchly in advance.
