10.6 breaks resourceforks when used in a (Windows) network with 10.5.8 (?!)

Question

Does this only happen to me ?
a file: filename.txt, which has a resource-fork when copied to a remote windows share (using ntfs filesystem) will not produce a "._filename.txt". However, the resource fork is preserved.
But, when you access this file using a 10.5.x or earlier client, it does not see the resource fork.
The other way around, the same problem appears.
To check this:
try this using a terminal on 10.6:
Create the file:
echo "1234567890" >test.txt
echo "theresourcefork" >test.txt/rsrc
check if the resource fork is ok:
cat test.txt/rsrc
result: theresourcefork
copy the file to the remote share ( in my case: windows 2k3 server) using smb protocol
rename the file to "test1.txt"
copy back to your Mac on 10.6
again check if the resource fork is there:
cat test1.txt/rsrc
result: theresourcefork
Now, go to your 10.5.x Machine
copy test1.txt from the network share to your computer.
check if the resource fork is there:
cat test1.txt/rsrc
result: (empty)
while it is nice, that 10.6 probably uses ntfs streams to preserve the resource fork ( a much smarter behaviour as before with the "._xyz" files), It completely breaks your data if some of it relies on resource forks and you use 10.6 together with older MacOS versions.
The best case is that you cannot open your documents any more on 10.5 or 10.6. All other cases are worse.
Apple should have built in a fallback compatibility or, should have printed a sticker on the CD.
WARNING: Do not use together with earlier versions of the OS in a Windows network !
I have this rather strange behaviour on 2 Machines, but have not checked if other installations have the same problem. But, I did not find anyhting here when I search for "resource AND fork".
Can anyone else try this out if the behaviour is really that destructive ?

Followup:
indeed, 10.6 uses ntfs streams when availible to store metadata.
for a workaround:
http://developer.apple.com/mac/library/documentation/Darwin/Reference/ManPages/m an5/nsmb.conf.5.html
create
/etc/nsmb.conf
contents:
\[default\]
streams=no
close all server connections, reconnect.
