Hubs

[xxxjay]

I would try to make every domain a "mini" hub of sorts on www.yourdomain.com. Since the index isn't listed with linklists you don't have to worry about changing it when you trade links.

The make a hub above that to link your mini-hubs and try to get abc trades there.

If you accomplish that build another layer.

If you get to where you have a lot of different domains I would reccomned spitting class c's.
