historic mailing list archives

Hi,

the mailing list search engine I emailed about earlier
(http://people.nokia.net/~lars/ietfsearch.html 
) only finds emails that are available in an HTML-ified archive  
(hypermail, mhonarc, pipermail, etc.)

Although most of our current mailing lists have such archives (esp.  
all the ones hosted on ietf.org), many historic working groups have  
archives that are only available in mbox format. If they are available  
at all - when I checked the screen scraped archive URLs on http://tools.ietf.org/wg/concluded 
  I was shocked how many are unvailable. It looks like we're in  
serious danger to loose some of our institutional memory.

So, I'm thinking about starting some concerted effort to collect and  
HTMLify the archives of historic IETF mailing lists. For example, I  
grabbed quite large number of them from
http://gd.tuwien.ac.at/infosys/network/docs/ietf.org/concluded-wg-ietf-mail-archive/ 
, and I'm getting ready to convert them via mhonarc.

Questions:

   - do people think this is a worthwhile effort?

   - where should I collect the archives and host the HTML from?
     (I'd prefer something at ietf.org rather than my own server)
