I agree with you on such point,
you don't want to create a new trend of virus/trojan/worm
to be EMCAscript/JavaScript based instead of VBA scripts!
Don't redo Microsoft Designer mistakes! =)

Thanks for reminding us and being the watchdog of such awful design 
mistakes! =P

I don't want my name to be associated with such idea! =)  No thanks!
[ 5 years later:  Who suggested that SVG have network sockets and led to 
1000 worms being spread on the net?  ahhhhhh!!! ]

I was more looking for an efficient solution,
XML-RPC and SOAP support are good enough for me.

What about an SSH interface?
Would that be targetted as safe or unsafe?

Therefore, keeping the secure transfer thing
and allowing people to write their own non-XML protocol.

Anyway, does someone really want to create their own protocol over SSH in 
JavaScript ???
It seems a major case of JavaScript abuse/torture to me, isn't it !?

Robin> If we provided the minimum TCP/UDP interface and users had to build

That would be too low level for me at least =)
Implementing FTP in C/C++ is quite something, doing it in JavaScript ?!? Are 
you serious!

Robin> Have you given thought to the security model?

Security on the data such as encryption (SSL) depends on the application 
Security as of the network interface that's a major issue that can't be 
ignored, as Randy put it.

(with the

time)" would

That would be a really awful way of dealing with the problem.
Like Randy says, I don't want a user to be prompt 2000 times by a 
SVG/JavaScript connection hook
inside an HTML document with embedded SVG to force him to connect to 
something he really don't want,
like some damn ActiveX webpage that do all sorts of nasty thing.

Talking to a Server via SOAP/XML-RPC looks more natural.
Worst case scenario the actual FTP/SFTP/SSH/IRC/NNTP/POP3/SMTP connection
is provided by the SERVER not the USER,
that would close the security issue, I think.
Since the SERVER could ensure that only some already known connection are 
unless it is badly written, but then the blame would be
on the SERVER not SVG itself for being insecure.

It would be also easier to have a real implementation on the SERVER
in Java, Perl, Python, C/C++ or similar, than some primitive JavaScript.
