I see it also has Openoffice - including a recent preview 1.9-2.0 and the 1.1.4

Official Blueyonder mirror link:
ftp://mirrors.blueyonder.co.uk/sites...loper/680_m69/
There is a tucows mirror at blueyonder, so I don't believe it's "restricted"
Blueyonder to NTL should be a solid and low cost route.
Many other ISP's have their own FTP server, and while some of them are still "open" (like demon) - some of the mirrors that would have been useful are now unmaintained - a LOT of out of date Mozilla mirrors out there!
