I guess the best trick would be to make a very simple intro page giving the surfer a choice between a flash site and a simple HTML site depending on his connection. At least this gives him the choice... Even if he as a highspeed connection doesn't mean he'll want to have the flash site... Some javascript also doesn't work on mac or on some browser... why take the chance to messup with a potential client?
nice work BTW Young... your designs are great... your Flash is great, but I prefer the HTML version tho...
Keep it up!
