Jake,
I think that DNET is probably here somewhere, perhaps a Sysop can help. I
did a quick check of the files in 'User and found this in LIB 5:
NETKEY.LZH/B 23K 17-Feb-90 Type on remote machines through DNET!
I think this may not be the whole DNET system. Haven't looked through the
files in 'Tech.
