Definitely. And, Sharepoint is unbelievable once you start using it. We use Exchange and Droid is connected to Exchange. It automatically finds the cert. I did forget to mention that you would need a public cert for RDP, but I figured you would know that. Much better to log in with a browser with remote.domain_name.com than to have to use an IP address.
Remote Web Workplace still has more options and is the most secure. Of course, it takes a few clicks though. But, it uses port 443 while Sharepoint which used to use 4125, now, in Microsoft's infinite wisdom, is now 987.
But, those are the big three: RWW, Sharepoint and Exchange all licensed with SBS. And, now, bundling RDP through terminal services into 443. This is what makes it so cool and much better than the "big boy" Windows Server 2008.
