What makes a nasty hack? If you have a static block of XML such as
char[]gmpi_metadata[] ="<?xml version="1.0" encoding="utf-8" ?><QQQQ GMPI
ONLY KEEP OUT>data...</QQQQ GMPI ONLY KEEP OUT>"; the odds of this data
being misidentified by GMPI or anyone else are absurdly small.
I don't think we're going to find an easier to build, easier to construct,
faster to read metadata scheme than this.

Thats true, in theory, but it is not partularly easy and will require
non-standard linkers* for plugin developement, which sounds like too much
of a barrier to entry to me. Its also one more platform specific thing as
it would have to be defined for ELF, COFF etc.
* I suppose you could put ASCII armour around the metadata block and place
it in the data segment of the DLL, assuming it wasn't encypted, but that
is just too nasty a hack for me.
