Homebrew PCBs

I've been wanting to add downstream USB ports to a few projects for some 
time.  To deal with this now and for the forseeable future, I decided to 
put a 4-port hub on a DIP.  The idea is that a so-called hub-on-a-chip 
is merged with its support stuff onto a piece of PCB the size of a DIP-32 
or probably a DIP-40.  To add downstream ports to a design, put this 
microhub after the female USB-B jack, then hang your gizmo[1] and female 
USB-A jacks off the microhub.

How many of you would be interested in something like this?  I have a 
quick-and-dirty schematic at http://frotz.homeunix.org/microhub/.  The 
.sch file is from gEDA and you'll need the TI symbols I just uploaded to 
http://www.gedasymbols.org/user/david_griffith/.

(http://obdev.at/products/vusb/index.html) loaded on it.
