There is a FAQ posted frequently which gives a list of all the files that are online at the vi archive. It also gives a list of addresses which mirror the vi archive. The main address is alf.uib.no, but it is archived at many, many sites. The vi-archive faq lists all of them. Please check that faq before ftping to it, as there is almost defiantly a closer and therefore faster site to you that the one in Norway.
A mirror site is available at: cs.uwp.edu /pub/vi, and another at monu6.cc.monash.edu.au/pub/Vi.
The site has many, many files on vi, including a few clones. It also has the UCB distribution of vi, and lots of useful macros. Check it out.
