No, there is currently no Linux filesystem with the NTFS semantics.
I think ext4 might have larger EA support, but there is no Linux
filesystem I know of with unlimited EA's and ACL support.

No Linux filesystem supports streams that I know of. Streams
are a really bad idea. Ted Tso convinced me of this when he
showed me a Windows machine running README.txt as a
binary (containing a virus of course). Streams are pretty
dangerous and mostly used to hide malware from admins.
