Oh, sorry, I see what your question is now...
I'm sure it'd help but teachers & school districts are funny about their
gradebook systems, it's worse than M$-addiction. The best analogous
example is when MS started marketing MS Money, they couldn't get into
the market very quickly b/c all the Quicken users wouldn't switch over,
even if MS gave MS Money away.... A school district's student database
& teacher's gradebooks are just like that... User lock-in is a funny thing.
The parts of a network least-vulnerable to user lock-in are the LAN
fileservers, etc., b/c the tech is transparent to the end user... This
used to be the case of Sybase on Unix vs. MS SQL Server on WinNT, there
was no functional difference (b/c MS SQL Server was rebranded Sybase...).
