I didn't receive the first one; thanks for re-sending it. I have to say, I have mixed feelings about the idea. However, no matter how hard I try, I can't seem to put 'em down in writing without clearly stomping way way out of the charter of this list, which prohibits flaming. But carving the odd excert out of my first reply: I'm not sure I see what's the advantage of doing up a whole new OS? You proposed
* The whole OS is small and doesn't include alot of baggage that is unnecessary for a FW machine.
but I don't think I see this. Unless you're just doing a router with packet filtering, you still need to support multiple applications running time-shared through a common IP stack, and so all of a sudden you need most of the functionality of a general-purpose operating system. Perhaps that can be done better than currently available choices. I'd personally be more tempted to look at say QNX than to try and do a custom OS myself from scratch. You also wrote
* Performance issues? (should be addressed by actual Java chips)
I think history suggests that custom chips don't make fast languages; indeed, custom chips can turn fast languages into slow ones. Easily 99% of the code I ever see run is written in C. Didn't someone do a sort of C-on-a-chip a few years back?
* Saleability (the marketing guys should love this one)
Now you've nailed an unassailable advantage. Truly stunning fortunes have been expended trying to turn Java into a silk purse. Ain't gonna happen, You Can't Get There From Here. But an infinite marketing budget can sell _anything_ to people who don't know any better, and I could easily see a firewall written entirely in Java riding on the coattails of the Java marketing crusade. -Bennett
