Wacom tablets through thin clients

Hello, we're trying to make Wacom Intuos tablets work through remote desktop on thin clients. The thin clients are Wyse R10L and D10D thin clients, all running ThinOS 8.0.522. We have the passthrough working fine (modified the wnos.ini to force the ID of the tablet through to the client, it's being picked up fine). The remote session (be it Server 2012R2 RDS or Windows 8.1 enterprise VDI's) picks up the tablet just fine, the wacom software sees the tablet, allows you to interact with the tablet, buttons work ect. What doesn't work is pen mapping. The pen will not move the cursor around on the screen. I moved cursor speed on the thin client down as low as it would go, and that actually made the cursor respond in the remote session (you can now tap, draw, and anything you'd normally do with the tablet). This would work fine, except the user can't actually see the cursor move. The mouse cursor stays in place until the user taps some where or is actively drawing. I'm guessing this means that we need to go yet lower with cursor speed, but we can't get any lower. I need some options! These must work in this environment (it doesn't have to work in both 2012 and 8.1, if it needs to work only in 8.1 VDI's I can spin up the few more we'd need for coverage). Please help!

My guess would be that the Remote Desktop cursor driver is "owning" the mouse pointer somehow, and thus the Wacom driver isn't able to operate properly. If you think about it, normally in an RDS session the mouse and keyboard are controlled by "special" "Remote Desktop" devices. These are probably not designed to co-operate with physical keyboards and pointing devices. I suspect that the tablet would need to be supported by the client, which would then pass the tablet tracking info through into the RDS session. This perhaps hints at this: http://blogs.msdn.com/b/rds/archive/2012/08/22/remotefx-multi-touch-for-windows-8.aspx
I'm not sure who you'd be best asking for clarification about this, probably Wacom, possibly Microsoft.
Wacom have a support forum at http://forum.wacom.eu/index.php which might be a good start.
If this is a solution that "must work" then you want it officially supported and verified, not fudged.

Thanks for the links! I had already posted on the Wacom Europe forums, no responses there yet. I will post over on the technet forums and see if anyone over there has some work arounds.

This info pointed us in the right direction. After asking Microsoft it seems the answer is they are simply not supporting it. They know it's a much needed feature, but they don't have any view of it coming in the future. Pens just simply won't work in RDS or VDI environments.

Sorry it wasn't the answer you wanted. I don't suppose you'd mind posting a comment with some detail about what you wanted to acheive and what MS said to my blog post here:
