I agree that it is relatively easy to do a protocol-specific proxy for
SQL or RealAudio, the point I was making is that there are a *lot*
of custom protocols out there, and trying to cover them all either
with a single "intelligent" proxy, or by application-specific proxies
would be unwieldy and expensive. If there were only two, we'd all have
done them by now. :)
Reminds me of the "Scenery Disks" for Flight Simulator; "please insert
your guglioplex proxy disk into drive A: and press return..."
