Yes, i saw it but when i've read Todd's mail i've hoped there was a 
trick with the stable release.
About updating, since i'm releasing a plugin i'd prefer that it's 
compatible with the stable release.
My syntax plugin uses p_set_metatada to write the value (it was you who 
give me this tips, do you remember? :) ), and for what i've understand 
the support for metada rendering in syntax mode is not in the stable 
release.
So at this point my stupid question is:
When users will upgrade from 2006-11-06 to current devonly, will those 
already created plugin metadata values be delete in pages that do not 
contain my plugin instructions anymore using a no-persistent parameter?
Thanks again,
Samuele
