I am not sure this is such a hot idea, or rather, I am not sure this is the way to do it. Nowadays, BITNET nodes have internet addresses which are likely to be used for a large number of recipients. If a particular node is going away, just removing addresses of the form "[log in to unmask]" won't be enough; if what you want to do is delete all users of that node from all the lists in the network, you will have to take care of the internet address as well, which of course is no longer available once the node is gone from BITEARN NODES. A second problem is that it is NOT clear whether you really want to do that: Case 1: the node is leaving BITNET but keeps an internet connection. In that case you should only delete the BITNET addresses or, even better, change them to use the internet address. Case 2: the node is basically being renamed, in that case you don't want to delete anything - just rename the addresses. The real solution is this :oldnode/:newnode proposal, but it has to be extended to cover the internet addresses. I'm also afraid I'm getting fed up at the amount of time I spend supporting "new format" BITEARN NODES things (which will bring a near-zero benefit to the end-user) when the activity I see on NODMGT-L regarding the introduction of this new format is almost nonexistent (ie although the Princeton people are doing a very good job at writing conversion and validation tools, there doesn't seem to be anything going on at the NIC regarding the *actual* introduction of this new format, and until the NIC is ready to exploit it we won't be able to introduce it).
