I think I qualify ;-)

The differences between mod_proxy and mod_ngobjweb are basically two:
a) streaming proxy vs non-streaming proxy
b) snsd support

Mod_proxy is a streaming proxy which passes on content to SOPE as soon 
as something is received. Mod_ngobjweb read the full request before 
passing it one to SOPE.
This is good, because SOPE is not (thanks god) multithreaded and 
therefore is blocked as long mod_proxy streams a request in (especially 
bad on slow connections). Also if a user does a large upload and 
cancels it, only Apache need to deal with it (with mod_ngobjweb in 
front, SOPE only needs to deal with complete, well received requests) 
;-)

And of course snsd support, the load balancer, currently only available 
with SKYRIX distributions.
