As per our email discussion, I support the addition of this provider
and propose Dave be given SVN access so that he can directly
contribute and maintain his work. Its really cool to have such
additions make their way into the QGIS code base!


It would be nice if possible for us (interested QGIS developers I
guess) to test the SQL Anywhere provider. Is there some way we can get
licenses of SQL Anywhere for personal use or is there otherwise some
kind of trial version that we can use for this purpose?
