- A list of URL's might work in some cases, but in general this means
- that adding a new mirror site requires updating all references...
-
- A name service sounds like a better solution -- bot how to integrate
- this in HTML or HTTP? And who's going to run the name service? Or
- could we use some existing name service? (Perhaps DNS is flexible
- enough to return a list of hosts for certain names, from which the
- client could choose? This would be ideal. Anyone know anything about
- DNS?)
