extending the maximum filename length

Has anyone using freeBSD ever increased NAME_MAX (filename maximum 
length) and have any experience with it?

We ($JOB) would recompile the entire system so intra-system 
compatibility would probably be ok, and we have our own filesystem 
which would support it.

But I wonder if anyone has tried it and hit unexpected problems.


reason:  Chinese and Japanese people who have gotten into the habit of 
having a filename of 256 CHINESE/JAPANESE characters in Microsoft and 
want to store their files on a FreeBSD based server witout having to 
rename everything. (3 bytes for each of those characters giving a 
limit of 83 characters).

(though since each character is a word the names if I could read them 
must be amazing)


NFS behaviour is one issue I don't know but would be interested in..  
could we SERVE such files?
