The Issue
So, as you certainly noticed, ICS-toting devices such as the Touchpad running CM9 do not offer the USB Mass Storage feature anymore.
On Windows, I hear that you can mount your storage using MTP (Media Storage Protocol)
On Linux and OS X, from what I've seen, there have been some attempts at building drivers for MTP but those seem to provide quite unreliable connectivity.
On Windows itself, it appears that the protocol takes quite a while to mount your device.
Google does not offer USB Mass Storage anymore in part due to the fact that you would need to unmount your whole storage from your phone to mount it on your computer.
The Solution
Alt Mounter! (I know, such an original name)
Alt Mounter is two things: 1) a small service and its widget, running on your device; 2) a helper running on your computer.
When you use Alt Mounter, mounting your storage on your computer is close to instantaneous. It works like a Dual Mount application; i.e. it does not unmount your storage from your device (it does not need to)
Platforms
Currently, the helper only exists for OS X. It should not take long to port it to Linux and/or Windows if there is a demand.
The OS X version requires you to install OSXFUSE or any other FUSE package. It does not install these drivers itself because many MAC owners have already installed FUSE one way or another (for instance, OS X running in Parallels will not require any extra installation)
GET IT
Alt Mounter is currently a beta product. I use it without problem daily on my Galaxy Nexus and my CM9 Touchpad but of course your mileage may vary.
Get it from the Beta Page.
