Ah, I don't think I explained myself clearly... the http-delta I-D uses
Etags for identifying old versions of resources so the server can send a
diff relative to this previous version. My question is, when does the
client find out these etags... e.g.

client has version X of file Y. To do an 'update' on this file,
according to the http-delta draft, it sends a GET request with
If-None-Match: "etag-of-version-X".

The specific case I thought about was after a checkin: the etag will
have changed, so it might take an extra round-trip to find out the new
