I was thinking the same, a few ice cold beer drops, and they could ask him if he can taste it. Edit: seems his requests could have been conceded through his feeding tube: "The first message was a simple thanks to Birbaumer and the rest of the team. Other messages related to the man's care preferences: asking for a head massage or for more gel on his eye (which was prone to dryness) and requesting a higher head position when visitors were present. He even made suggestions for improving the performance of the spelling system. Eventually, he could make specific dietary requests for his feeding tube: soup with meat, sweet pea soup, and curry with potato. And he did request a beer and for his caretakers to play his favorite band, Tool, very loud." Unfortunately he's locked-in because of progressive muscle atrophy, so recovery isn't likely.
