Can VarAC gateway between two VARA FM LANs?

I'm working on a book that will feature VARA FM as a chapter, and VarAC as another chapter.

It occurs to me that there are situations where it could be advantageous to have sepearate VARA FM local area networks in the same area that don't "see" each other. Example, a group of high power VARA FM WIDE stations operating on a UHF frequency, and another group of VARA FM WIDE / NARROW stations operating on VHF.

I understand that VARA FM WIDE and VARA FM NARROW stations can interoperate on the same frequency.

In my hoped-for scenario, two VARA FM applications (with different radios connected) could "recognize" each other as a VARA FM digipeater and thus forward all VARA FM data between two VARA FM LANs.

But, I don't see such a capabiity in the VARA FM application. Thus I'm wondering if such a capability exists in VarAC because most of my imagined utility in an inter-LAN gateway function are the higher level functions such as email, messaging, file transfer etc. are capabilities of VarAC rather than built into VARA FM.

I'll guess that the VarAC email capability could be configured to be able to transfer email between two different VARA FM LANs, but again, I'd also like to be able to transfer text messages, file transfers, etc. between the two LANs.

Thanks for any help with this scenario.
