Some more information: If I look at /e/usr/share/man/man3/ with 
Windows XP (File) Explorer, the :: files are in fact visible, but I 
cannot operate on them (for example, copy and paste) without getting 
error messages. So Ext2fsd is serving up the files, but some other 
part of the system is balking at the names.

I guess /bin/ls is similar in the sense that it "sees" the file, but 
when it tries to list the name, it runs into some restriction.

I wish there was a way to disable the restriction, maybe even just 
temporarily or on a per-program basis...
