If your bluetooth adapter is usb-connected it will take a kernel patch to get multiple simultaneous connections. If it's uart-connected (typical for embedded) then it will work without patching. either way you will be writing your own userspace software to copy audio around and negotiate connections. -- Brad ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
