www.ekahau.com is another one

!Unrelated to Surveying:
they also do a cool wireless positioning engine!
claiming 3 feet accuracy in the best case.
(I'm still wondering how they do that!)

but if you wait a little bit we are designing an open-source one
(not surveying but positioning)
to leave annotations geographically
the web site is not up yet but it will be www.where-fi.org/net/com
we don't have 3 feet accuracy...so far about 20 feet!
if you are interested you can read  a preliminary descriptionon at
www.gpster.net
