Lycos Group has early on invested a bit in Fast, as has Dell BTW. If I remember correctly Lycos has a seat On Fast's board of directors.
As discussed here http://www.webmasterworld.com/forum4/276.htm [webmasterworld.com] Lycos network provides the ads run on Alltheweb. Many of which are ads for Lycos properties. Furthermore Lycos will act as reseller for Fast's PFI programme. The Lycos Group is Fast's most important partner for their websearch divison.
