But isn't part of the client's job to do the reverse also?

You've focused on allowing the client to change
	#UID:10386 says: 'Heya'
to
	Boffo says: 'Heya'

But at which point do you change

?

If the client does it, then the server needs to be able to map the
 client's idea of a UID into the server one.
Either your function is two-way, or you need to do brute-force to
 find the object.

If the server does the remap, then what's the point of the client
 storing the data?
