hello again--

	Thanks for the info!

	I think performance will suffer if the Squeak VM continues to poll for socket events.

	Lest someone joining the conversation here think this is only the issue, I'd like to reiterate that it is not. There are several more important issues. Squeakers, please see the webpage for my complete argument.

	Does the iCruise pose a special challenge?

	I do think the current primitives are inherently flawed. The "accept" problem is another relatively minor issue. Again, I urge Squeakers to read the comparison webpage.

	I think Correspondents provides a very good implementation (NetStream), which incidentally works with all external resources, including sockets, files, serial ports, etc. Correspondents also provides a  client and server framework which uses it to good effect, and could be the basis of robust and easy-to-use reimplementations of Squeak's current internet clients and servers. I'm interested in speaking with anyone with related ideas.


	thanks again,
