TS Gateway support for Mac?

With Windows Server 2008 Terminal Services you can utilise the Terminal Services Gateway Server to allow RDP access over 443, eliminating the need for VPNs or firewall re-configurations for external users.
On windows, you need the RDP client 6.1 to use TS Gateway Server.
On Macs, it appears you are out of luck: Microsoft's RDP client for Mac v2 does not support Gateway Server.
Is there any RDP client available for Macs that support Gateway Server?

Solution 1:

I don't necessarily have a definitive answer but I can tell you that I've had cases open with Microsoft Support to deal with various implementation problems where the initial MS response was to use TS-Gateway and RemoteApp. Which I had to bring up that my non-windows clients would be excluded from this solution. In none of these cases were we able to find a Mac or Linux client that would provide access to these features. Further my requests for a road map on the Mac client support have as of yet gone unanswered.

There was some hope I found for a possible work around with an unsupported beta Silverlight version of the TSWeb services. Unfortunately, I never was able to work through testing or implementation of this. Various other posts and docs indicate it should be possible to allow non-windows clients to be able to connect to a farm essentially through a ts-gateway and even leveraging Remote-App. But I can't confirm or deny this to be true.

I keep hoping I've missed something but so far this is all I've found on the subject.
