From an engineering standpoint you absolutely must have at least one redundant channel, with an acknowledgement mechanism (e.g. registered mail). But fax is also possible for this because the receipt is stamped with date/time of reception. This is easily monitored for continuing validity using the kind of automated checks I mentioned recently; no human involvement required at sending end, only at the receiving end to return the token (manually, ensuring that someone is actually managing the public resource in his care).

As Denis explained in his mail, this channel exists as far as the NCC is concerned (at least for members). It's the Billing Contact which is contacted at least annually and the token returned is "money". If it isn't returned, 120 days later the LIR becomes an ex-LIR. rgds, Sascha Luck
