Sure, yeah.

  class Shoes
    def remote_image uri, opts = {}, &blk
      uri = URI(uri) unless uri.is_a? URI
      uri.open do |fin|
        name = uri.host + "." + fin.meta['etag'].gsub(/[^\w\-\.]/, '') +
          File.extname(uri.path)
        cache_path = File.join(LIB_DIR, name)
        unless File.exists? cache_path
          File.open(cache_path, 'w') do |fout|
            while chunk = fin.read(16384)
              fout.write chunk
            end
          end
        end
        image cache_path, opts, &blk
      end
    end
  end

This will be in Shoes soon.  I just need to make some caching decisions.
