Simon,
Licensing is complicated and does have anomalies eg I understand that hdfs:// exporting nodes do not need a server license yet nfs:// exporting nodes do. (someone can correct me here if I am wrong but I have seen recent diagrams that show exactly this).
In your case, i think there is
Pretty easy to determine experimentally, with a few trials
And the answer is 3876 for an simple file with just a selinux EA which is
apparently created by default on my test system.
So apparently there are actually only 220 bytes of metadata in this case
(4096-3876=220).
As they say YMMV ;-)
Does anyone know whether WebDAV protocol access support will ( if ever ) be
implemented within GPFS ?

No, but (I think) TCT uses some of the EA space in the inode to indicate that
the data is in the cloud tier.
And yes, it does copy the data blocks in the inode to the clod tier if you
migrate it.

Would you tier an in-inode file to the cloud?
I mean, I wouldn't tier an in-inode file out to tape?

TCT doesn't use dmapi though I thought?

About 3.5 KiB if the inode is 4k and you are not using encryption (uses EA
space) or large custom extended attributes,

I have a question about licensing.
If I have a system which is NFS mounting (from a CES node), that is then
serving data via HTTP, does this system need to have a Server license?
