Nice idea!
One of the reported issues with the Raspberry Pi is failure of the SD card if power is interrupted while the card is being written. Does your implementation overcome this problem?

Of course the eMMC is still based on flash, which has a limited lifetime. So we use a customized version of Raspbian which has swap disabled by default (can be enabled if you need it) and tunes the syslog configuration to reduce the amount of log data written. It's also possible to use a tmpfs-backed /var/log (can be enabled with a mouse click or a simple command). That way we try to prolong the lifetime of the eMMC as much as possible.
We've also been in talks with the Foundation about this and they have asserted that the eMMC is of good quality and should last for the typical lifetime of a PLC (which can be decades).
