	And that means that I don't agree with Dave on that part, I was just
asking if there is some kind of specifications for embedded systems API
to have even a little compatibility and portability between that boards,
like some standard services: memory alocators, equipment list, device
list and proprerties like in I or O or I/O, is analog, digital, serial,
network, timer or so, range of values, interruup services made simple,
interrupt priority alocation map, watch-dog presence and programming and
a simple way to specify priorityes on those loaded tasks and yes, even
some standard routines for upgrading Flash on serial or network
interface, this last thing sickens me, it seems that every board has his
own proprietary way to be updated. This is great for loocking users with
you, and give nothing to the competition but here we're laking about
Open ( even Free like in FSF if we join the GNU project :) things.
	So if you (or others) plan to do something like that I invite you to
join forces NOW !!!
