Dear George,
First I would state terms as following:
* Sharing HW - using the same hardware by different domains using PV
drivers, so actually one domain accessing the HW directly and serves
other domains.
* Assigning HW - providing access to some particular HW for some
particular domain. E.g. peripherals by default are assigned to Dom0, but
using Passthrough some could be assigned to DomU.

Our plan is to run Linux as Dom0 and Android as DomU. The Linux
portion will be having 1 HDMI display and the Android porion will be
having 1 HDMI.
Can we share the DU and use the HDMI port as it is in the guests?
IIRC last year it was shown a setup with Salvator-X board, where one
HDMI display was *assigned* to Linux (Dom0) and one HDMI display was
*assigned* to Android. So such setup is technically feasible.
If a domain has assigned a display to use solely, it can share that
display to other domains using displif protocol [1].
