Charlie,

	This morning I was pretty down on SMIL, but this afternoon I've had more
time to explore the links you provided, and am currently downloading free
software that promises WYSIWYG use to produce the code. Ahhhh. And I read
up on what SMIL is supposed to be able to do when it's fully developed, and
I get a strong whiff of "Educational Applications" from it. Seems like SMIL
could be used to make web presentations of materials to be learned, as a
stand-alone, or as part of an educational site... Something that could
make, oh,er,a lesson, group of lesson, or even a whole (basic) school
online.... 

	Seems SMIL could be a worthwhile investment of some teachers' time to
learn it and make it grow... 

	What would be the problem with having full-screen streaming video? Too
much bandwidth and cost? Is the cost at the server end or the user end? 

	Oh, this afternoon I spoke at the faculty meeting, announcing the county's
website, and what was happening at the other schools so far, and asking
this faculty to consider who wanted to do what. I've a volunteer to do the
Pre-School program (including the pre-school handicapped kids, the at-risk
kids, and the head start kids), and another to do the Kindergarten classes.
The one for Pre-School did a web page for a community college class, and
made a webpage in Word, which she is now maintaining on Geocities. The
other has just been given a computer from her husband, and told to learn to
use it... So, these are my first two "students" in a faculty of
forty/fifty. The others undoubtedly shared sighs of relief we were happy
with two volunteers the first time it's brought up ... 

	Well, I better dust off my scanner.... I promised I'd scan student work
for the website for teachers, and I hope I will be taken up on the offer...
<grin>. The download is finished, and I need to go see if SMIL is ready for
teachers to use.... If I can learn it, other teachers can too... 

					Anne
