Broadcast over IPSEC Tunnel via ASA? Is it Possible?

Possible to send broadcast from a specific IP over IPSEC VPN via an ASA5505?

I have found the ASA does not support a GRE tunnel and that GRE is needed to send a broadcast to the remote site of an IPsec VPN. Anyway to accomplish this?

The scenario: a client has a networked scale that sends out a broadcast.  The management software picks up on the broadcast which allows it to work.  They have recently moved over to a virtual environment hosted remotely at a DC.  I'm looking to get their scale to be visible to their virtual desktops.

You can upgrade your ASA to 9.7 and configure IPSEC using VTI which will
give you this option

Looks like the latest possible version to install on the ASA 5505 is 9.2.4...
Unfortunately it looks like I am unable to use the VTI interface.

Looks to me there there is not a way to send broadcast packets over VPN with this model ASA.
