We did look at this (with Drummond) in December. The bottom line is that it can't be done easily - a mechanism similar to XRI's canonical ID verification would have to be employed, to confirm that the i- number actually 'belongs' to the URL on which discovery was initiated. (Otherwise anyone could put any i-number in their URL- based XRDS files.)
