MARGINALIA has invited many of Geza Vermes's colleagues to publish brief tributes to him at a dedicated web page on their site. A number of them are already up, mine included: Tributes to Geza Vermes, June 22, 1924-May 8, 2013. Many thanks to T. Michael Law for organizing this.
By the way, I count about 60 references to Professor Vermes in a decade's worth of PaleoJudaica archives. Many are in passing and of little interest, but some of the substantive ones are here, here, here, here, here, here, here, here, here, and here.
