Could this be implemented as a first priority to daemon. If it turns out

Is the daemon an implementation of the TCG resource manager spec?
The TCG spec does use a daemon approach, similar to tcsd for TPM 1.2.
The Linux TPM driver is currently using a different approach, a
in-kernel (in the TPM device driver) resource manager.
The advantages I see to putting the resource manager in the device
driver are:
1 - Kernel uses of the TPM go through the same device driver, so they
leverage the resource manager.
2 - The TPM device driver offers a standard /dev/tpmrm0 interface,
100% compatible with /dev/tpm0.
