Has anyone been able to successfully connect to your company's email (Outlook) via Antha/Movian VPN ISPSEC Client from a Treo 650/700 running Palm OS?

What application works best for viewing web pages on your corporate network?

IF yes, then how did you set this up? Are there any gotchas?

Are there any other alternatives to retrieving mail and getting to corporate resources via the Treo device?
