A follow-up on the story that follows (wow, was that quick!): I.Am-KingPin sends word that the post about the 1000 skin limit is in error, (meaning the Kingpin Skin Registry is obsolete in a few short hours). It turns out there is a workaround that they've posted involving the "skin" console command which allows for long skin filenames in Kingpin and eliminates the 1000 skin limit.
