[Libreoffice] Slowness on UNC path

Dear LibO devs, 

A little x-post (sorry) in case some of yous don't read ooo-dev. 
I haven't tested it yet with LibO, but I'm afraid it misbehaves the same way. ( I would be 
delighted to be wrong, though)
I think the issue is quite serious and might be a real blocker for corporate deployment.

I'd like to have your opinion on the issue 105283.

http://www.openoffice.org/issues/show_bug.cgi?id=105283

In a nutshell, when working with a file using a UNC path, OOo sends a request on
port 80 and waits for an answer (at the opening and closing of the file). A
problem occurs when the port is in stealth mode, OOo waits till the timeout,
which means the application is frozen for 30 seconds or so, which is not
acceptable from a user pov.
I became aware of the problem when one of our client switched his servers to Win
2008 server, where stealth mode is set by default. So I imagine that the problem
will spread quickly.

Are you already aware of this? (the issue is not confirmed at the moment)

Could any of yous give me a rough estimate of the efforts to fix that?
If you can also quickly explain why OOo behaves this way, that would also help.

Thanks,
Camille
