This is great piece of kit (on OSX) and I think it's possible to get more than is working currently (pointer and press to left click) on Linux.
On Ubuntu 16.04, find out the bus number of the (plugged-in via USB) tracking pad with lsusb -v
e.g.
Bus 003 Device 002: ID 05ac:0265 Apple, Inc.
Change to root user (sudo su root), enable usbmon with modprobe usbmon and then you can cat /sys/kernel/debug/usb/usbmon/3u (or e.g. 4u if your bus number was 4) and tap/move about on the trackpad to see output. Here is some sample output (just from tapping, not clicking):

The trackpad constantly emits 'lines' where the last byte is always 00000001 when your finger is on the trackpad (stationary or moving about, sometimes even when just hovering a millimetre above). But one or more 'lines' with the last byte changed to 00000000 are emitted when you take your finger off the trackpad. I'm not at all familiar with USB or mouse/trackpad drivers but this indicates to me that tap-to-click should be achievable? About whether multitouch and other features are locked down I'm not so sure
