I'll be posting the socket and netinet changes to RW>arch@ today; I've posted them previously to other lists, such as current@. Skip Ford expressed interest in netatm, but he said also that he would continue to work on HARP even when it is removed. So I guess it could be revived in the future (just in the case). I've also sent him my half -IDT driver and he said he will first work on this. When this is ready we have all the hardware supported in ngATM which HARP also does. harti
