Hey- I just wanted to let people know that after searching the internet and emailing and such, I have obtained all the firmware needed to convert an aironet 630-900 into its bridge cousin the 640-900. As it turns out, I didn't need the firmware since the 630's I bought on ebay already had had the firmware upgrade done. Anyway, since the firmware wasn't easily obtainable anywhere on the internet, I've mirrored it on my webstie at
