This will negate one of the strengths of sane (few frontends supporting lots of backends). I wonder if there is another approach here- middleware? Similar to how backends are unaware that they are being used over the network with saned, perhaps we could have a kind of intermediary poller, which ran on the machine with the scanner? It could emit events, and not require all backends which support buttons to be updated? allan -- "well, I stand up next to a mountain- and I chop it down with the edge of my hand"
