That was assuming that the two software components likely to fetch  
DTDs or Schemas actually supported the use of a caching proxy. A bit  
more research later, I could not find authoritative info on whether  
libxml2 does, but as far as OpenSP is concerned, the news are not good:
http://sourceforge.net/tracker/index.php?func=detail&aid=1748536&group_id=2115&atid=352115
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=353220

This unfortunately makes the idea of using caching proxies instead of  
catalogs/entity resolvers moot. The (thin, I admit) hope is that  
adding proxy support seems to be on a possible roadmap - at least  
according to this 2003 thread:
http://sourceforge.net/mailarchive/message.php?msg_id=1041881661.1314.8.camel%40kerberos
So maybe if someone wants to give it a shot...

In the meantime, the validator release is still scheduled for Friday,  
but without proxy support.
