"Stark" regulations

[Belgarath]

Anybody know anything about the new "Stark" regulations that take effect in January of 2002, specifically regarding any effect on qualified plans? As far as I know, (and my knowledge is severly limited on this!) they do not supercede ERISA, nor the normal IRC rules and regs pertaining to qualified plans. They may have effects(major/minor - don't know) and cause employers to make changes to the entity structure and ownership arrangements in various medical practice situations, but that can be dealt with under the existing rules for qualified plans.

All opinions appreciated.
