I am the Exchange admin. We can't guarantee that people are using a third party app, that's why we want native remote wipe, like the HTC 2.1 has. This is getting ridiculous that these features are not included. (Or, if there are, someone point me to a list. I'm told that 2.1 is 2.1 and then I'm told HTC has it, Google/Moto Droid doesn't... ?!)I'd recommend getting TouchDown - it supports the security requirements that your Exchange Admins have put into effect, remote wipe, and much more.
