Well, I don't care much myself.  I have no use for that capability, even 
though this was interesting to implement.  So it only depends if someone 
relies on this or not.

A few months ago I asked on the list if XIP was still useful, and Tim 
Bird replied that Sony was indeed using it.  So if this is not too hard 
to keep this feature alive then I'd go with that option.
