We were working on a Mate release with QueryVM some time back, but it
fell by the wayside. However, it was mostly ready to go (missing some
testing, problably some documentation).

The current state can be found in tinyos-1.x/tos/lib/VM, under CVS on
sourceforge.

Some documentation on QueryVM can be found in
tinyos-1.x/tos/lib/VM/languages/tinysql/tinysql.txt

It *should* work on mica2, micaz and telosb (the *should* bit refers
to the fact that some testing was missing ;-)). Also I haven't tried
this in a while...

Phil and I talked about doing a TinyOS 2.0 port of Mate. Not sure
if/when it will happen.
