You're already competing with your immendiate neighbors for a fixed pie of cable bandwidth. You have a better shot with DSL, if you pay for multiple DSL lines. In that case, you can set it up so some of your local hosts go to each DSL link, by ipfw and natd rules. However, what you can't do is have a single TCP connection on a single local host use both external lines. That would require at a minimum cooperation from your ISP which they are most unlikely to provide. -- Barney Wolff http://www.databus.com/bwresume.pdf I'm available by contract or FT, in the NYC metro area or via the 'Net.
