The Bleeding Edge

As time goes on, I come to realize more and more, that I always seem to look for solutions on the bleeding edge.

I am currently looking for the following solutions that do not seem to yet exist!

1. A USB device that allows me to take a Single USB drive and share it with the USB ports on two computers. I am NOT looking to network the machines, over USB or otherwise. It seems re4asonable that in this day and age such a solution would already exist, but it does not. Why would I want this? Well Imagine a USB drive connected simultaneously to your computer and to the USB port of a DIVX compatible DVD player. As you write a file from the computer, you may stream audio to your stero from the same USB hard drive. Alternately you may connect to a USB network device such as the Linksys SLUG , while connected to your DVD player.This may also be incorporated to a USB hard disk case to allow simultaneous access from two host controllers. This may be easier if one device is tagged as "read only" as in the case of the DIVX compatible DVD.
   
2. A "Smart" USB to Ethernet adapter. What this Ethernet adapter does is emulates a hard disk from a Windows or NFS network. It is reasonable that it would need some kind of a programming interface such as a mini web server to configure network parameters; Workgroup and shares to connect to, or perhaps with a utility through the USB port. This would also be useful on one of those DIVX compatible DVD players to stream DIVX video to your TV or MP3s to your stereo system via a DVD players USB port (which works only with a USB Disk)
3. Accessible HDTV modulator / Encoder. I mean a simple device that can take a HDMI or similar signal and produce a HD modulated "TV Channel" that can be used with the built in tuner on an HD TV. Ideally this would allow several to be used on different channels. There are many CCTV systems that will be undergoing upgrades in the years to come.

I place these items here and hope that someone may comment about anything that thry may know of!
