Yah, I'm evolving rapidly, the meteor trajectory of @mac.com
is quite predictable, "So long and thanks for all the Fish!"

Re "smart-host": I try to remain purely a client these days, server  
sysadmin is tedious,
and sooner or later all the b0rkarge needs to be dealt with client
side anyways, including parsing HTML in rpm, sigh.

BTW, while I have yr attention, is there any way to force Content- 
Length:
to be returned from a server? Stat(2) is currently returning a very  
"sparse" 0xffffffff, which
is accurate even if arcanely obscure ...
